Police said earlier that the suspect was wearing "military-style attire".
We've heard a bit more now from Katarzyna Cislo, a police spokesperson, who says that the suspect also "used military weapons".
"Many pieces of weapons and ammunition were found in his vehicle", she adds.
Four women and two men were killed in the shooting in Krakow's Main Market Square, according to local police.
The number of people killed in the shooting has risen to six, local authorities say.
At least 15 people are injured, officials in the Lesser Poland region say, adding that they are "receiving medical care at hospitals in Kraków" and that Governor Krzysztof Jan Klęczar is visiting the scene.
The Polish interior minister earlier confirmed two police officers had been injured, with one undergoing surgery.
New images show police cordons in place along Krakow's Grodzka Street, which links Main Market Square to the Wawel Royal Castle on the Vistula River.
Shop windows show signs of damage, seemingly from bullets, with glass shards scattered along the floor.
As our BBC Polska colleague Madga Mis reported earlier, there's still a heavy police presence in the area.

Image source, Getty ImagesPrime Minister Donald Tusk has praised the "heroic police officers who risked their lives" to stop today's shooter.
As a reminder, the interior minister earlier confirmed two officers were shot - one remains "in very critical condition".
Tusk also appeals to colleagues "of all stripes: do not exploit this tragedy".
"We will establish all the circumstances of this crime," he adds.
Officials in Poland have identified the suspect as a Polish citizen, according to a press spokesperson for the country's interior ministry.
Malopolski Police adds that the only known perpetrator of the incident is in police custody, denying reports that another suspect is being sought.
The police also deny reports that an officer has died.
Polish Interior Minister Marcin Kierwiński says one of the police officers injured in today's shooting is "in very critical condition".
Kierwiński says the officer suffered "three gunshot wounds" and "surgery is under way". He confirms a second officer was also shot.
"Police officers in Krakow risked their lives to intervene. Immediately. Thanks to their heroic actions, the attacker was quickly apprehended," he writes on X.
A tram operating on route 1 of Krakow was shot at from "a passing car", the city of Krakow's official social media account says.
Citing the Krakow's public transport operator MPK, the city's account says the shooting took place at All Saint's Square - a short walk from Main Market Square - and that the driver's cab window "was shattered".
"None of the passengers or the driver were injured," the city adds.

Image source, EPA/ShutterstockThere's a heavy police presence here in central Krakow, with the main square now cordoned off. I've also seen police officers driving around the city, as well as fire trucks and ambulances.
This is the main square in Krakow. It's very popular with tourists - there's a lot less of them around than in the summer but when I passed through several hours ago, the square was full of people.
It is surrounded by cafes, bars and restaurants and it's a Saturday so normally you would have a lot of people in there.
Now, it's unusually empty as police are not letting anybody in. I can still see people coming out from behind the police cordon too, as officers are sending them away from the square.
Image source, ReutersAn eyewitness has described how she saw a man in a car who started shooting.
Tali tells Reuters news agency that she ran inside a restaurant and wanted to wait upstairs until they heard "silence".
But she says no silence came, because next she heard the noise of a helicopter - likely the emergency response.
"I don't know what to do now", she says, explaining that she doesn't know how best to get to her hotel.
We're hearing more from Polish police in Krakow.
"According to information from police officers, the man was wearing military-style attire," a police spokesperson says.
"During the arrest, officers used their weapons, but the man returned fire; as a result, two police officers are among the injured."
We're now getting more pictures from Krakow's Main Market Square, where the shooting unfolded.
Pictures show members of the public observing the scene from behind a police cordon.
Another photo shows a person waiting for treatment inside of a shop, the floor littered by glass shards.

There are a lot of police, but they say they won't talk to me.
We can now bring you comments from Tom Rose, the US ambassador to Poland, who says there has been a "horrific mass shooting in Krakow".
He describes it as a "savage and murderous attack that's shattered the peace of Poland".
"What we know so far is that several innocent precious lives were viciously cut down on a Saturday afternoon in Kraków’s historic and iconic central square," he says in a post on X.
"America stands with Poland at this dark hour as Poland stands with her beloved citizens of Krakow. May the blessed memory of those lost today assuage the grief of those who mourn."
Polish President Karol Nawrocki says he is "deeply concerned by reports of the tragic events" in Krakow, and that his thoughts are with victims, those injured and their families.
"I remain in contact with the relevant authorities and expect a full explanation of the circumstances surrounding these tragic events," Nawrocki says in a post on X.
"The head of the National Security Bureau is on his way to Krakow. The safety of Poles is an absolute priority!" he adds.

We now hear that Kierwiński is heading to the scene in Krakow's Main Market Square, according to a spokesperson for the department.
