A 24-year-old Muslim man was in police custody Sunday after a threatened shooting at the London Muslim Mosque.

The mosque was disrupted after noon prayers by a man whom police say uttered threats when asked to leave.

“Shortly after 1:30 p.m. we received 911 calls from members of the London Mosque indicating there was a male there who had threatened to shoot members of the mosque,” said Staff Sgt. Ryan Scrivens.

“It was of extreme concern. We dispatched multiple officers who arrived there shortly therafter and we were able to arrest a man.”

No firearm was found.

“He was threatening to come back and shoot members of the mosque,” said Scrivens.

Police aren’t sure why the threat was made. More than 15 officers arrived at the mosque.

Sources close to the mosque, who declined to be identified, dismissed any suggestion of racial or religious violence, saying a man asked for and was given food, but things escalated when he asked for money but wasn’t given any.

No charges had been laid, but the suspect was arrested on suspicion of “uttering threats of causing death,” said Scrivens. Police aren’t looking for anyone else.

“We are now convinced this was an unarmed person,” said Nawaz Tahir, a spokesperson for the mosque.

No increase in mosque security is planned.

”We are in that environment, we have security around the mosque, police assist us regularly with security protocol,” said Tahir.

A Jan. 30 shooting attack on a mosque in Quebec City killed six people dead and wounded 19, making police vigilant whenever they receive a call related to a mosque.

“Given our current climate, in our society, this causes concern,” said Scrivens.

The investigation continues.
