A gunman is suspected of shooting and killing his father in downtown Helsinki close to the Finnish capital's central rail station, police said. No one else was wounded.

The shooting Monday afternoon had caused some panic in the streets.

The suspect — "a young man of 19 or 20" was caught near the scene and did not resist arrest, police said. A witness, Jawhar Mustafa Bashda, told the Helsingin Sanomat daily that he chased a man who came running out of a restaurant, caught him and handed him over to police.

Bashda said the young man "said he had killed his father ... because his father had done so much bad to him during his life."

Police gave no other details pending an investigation.
