Police are investigating after a hand grenade was detonated in Amsterdam’s Rivierenbuurt in the early hours of Monday.

Neighbours were woken at around 4.15am by the loud explosion in Oude-IJsselstraat. Nobody was injured and there was no fire but several cars parked in the street were damaged, the Volkskrant reports.

One witness told police that a boy wearing a black hood was seen cycling away from the scene straight after the explosion, but he has not yet been traced.

The incident happened near the scene of a fatal shooting which took place an hour later in Bijlmermeer, where a man was killed with what police suspect was an automatic weapon. Police have given no indication of a connection between the two events.
