Berlin — A teenager suspected of attacking 28 people with a knife in a rampage in the German capital has told police he had been drinking heavily and could "remember little" about what happened next.
"We're in the dark about the possible motive," said Gerd Neubeck, the city's deputy police chief. "He denies being the one that caused these injuries."
The teen's denial comes despite dozens of witness statements and the seizure of the weapon, officials said Saturday.
The 16-year-old student is suspected of stabbing and hitting dozens of people as he mingled with crowds heading home after a light-show Friday night to celebrate the opening of Berlin's new central railway station.
Fifteen of the 28 adults injured needed hospital treatment, including several whose lives were saved by surgery.
The attack comes amid a rash of hate crimes in Germany that have raised concern about security two weeks before the country hosts the soccer World Cup.
