Story highlights 15-year-old asylum seeker stabs refugee center worker to death in Sweden

Authorities say the 22-year-old victim worked at a refugee center where the suspect stayed

"We think it might have been an accident, or there was a fight," a police spokesman says

(CNN) A 15-year-old asylum seeker stabbed a refugee center worker to death Monday in Sweden, police say.

The boy, who is in police custody, has not been identified, though his country of origin is known, said Hans Lippens, a police spokesman for the Västra Götaland region.

The incident happened at a home for asylum seekers younger than 18 where the boy was staying, about 6 miles (10 kilometers) from Mölndal town center, in the Gothenberg region of western Sweden. The victim, a 22-year-old woman, was alone with eight young male residents of the home, Lippens said. Only one is believed to have been directly involved, though police are questioning the seven other boys.

"This was not terrorism. We think it might have been an accident, or there was a fight," Lippens said. He added that police would release more information Tuesday, but because the youths are from different countries, they need various translators to interpret their statements.
