Swedish police released new pictures Sunday of a man who matches witness descriptions of the assailant who stabbed to death Foreign Minister Anna Lindh (search) in an upscale department store.

The release of the photos from surveillance cameras came as police questioned and released several people in connection with the slaying of the foreign minister.

The photos from the surveillance camera show a man clad in a blue baseball cap and a gray hooded sweat shirt, a Nike logo clearly visible.

Unlike previous pictures released by police, the photographs were not altered to hide the face, which is partially hidden under the baseball cap. The surveillance cameras did not capture the attack.

"We want the public's help to identify the man," police spokesman Mats Nylen said.

The man depicted in the photos matches witness descriptions of an acne-scarred man with shoulder-length hair who appeared to be about 30 and Swedish, investigators said.

Flowers, notes and candles were placed in front of the department store where she was stabbed Wednesday, while dozens of people waited to sign a condolence book.

Police said they were seeking 10 people with criminal records and previous offenses, and there were at least two of particular interest, spokeswoman Stina Wessling told The Associated Press.

A forensic laboratory continued searching for DNA from the red-handled craftsman's knife used to kill Lindh and clothing the murderer tossed away as he escaped.

Lindh was a prominent euro supporter, and her death cast a shadow over Sunday's voting, but authorities have so far said her death did not appear to be politically motivated.

The attack shocked a public still haunted by the 1986 murder of Prime Minister Olof Palme (search) as he walked home from a movie theater with his wife.

The killing of Lindh occurred only blocks from where Palme was shot to death 17 years ago and both cases have undercut Sweden's image as a safe society where few public officials travel with security details. Like Palme, Lindh didn't have bodyguards when she was attacked.
