WARSAW, Poland (AP) — Polish police have arrested a 16-year-old male on suspicion of attacking a synagogue with Molotov cocktails and said they plan to ask prosecutors on Thursday to open an investigation.

The Nożyk Synagogue was attacked around 1 a.m. on Wednesday, sustaining some damage to its facade. Nobody was in the prayer hall at that time and there were no injuries.

Police in cooperation with the Internal Security Agency arrested the 16-year-old Polish male in Warsaw on Wednesday evening.

“He was completely surprised, he didn’t want to talk, he didn’t reveal his motives,” police spokesperson Robert Szumiata was quoted as saying by the news agency PAP.

Szumiata said police will send a request to the prosecutor’s office on Thursday to initiate an investigation. The teenager, who has no previous police record, could face up to 10 years in prison if convicted.
