A California mosque was set ablaze in ‘clear homage’ to the New Zealand terrorist attack

Local and federal law enforcement launched an investigation into an alleged arson attack at an Escondido, California, mosque early Sunday morning, where the suspect left behind a note referencing the terrorist attacks at two mosques in Christchurch, New Zealand, that killed 50 worshippers.

The fire broke out at 3:15 a.m. at Dar-ul-Arqam in what authorities are investigating as arson and a hate crime.

"If its an arson, it’s possibly a hate crime as well," Escondido Police Department (EPD) Lt. Chris Lick said.

EPD; Escondido Fire Department; Bureau of Alcohol, Tobacco, Firearms, and Explosives; San Diego County Sheriff’s Bomb/Arson Unit; and the FBI responded to the scene.

Yusef Miller, a member of the Muslim community in Escondido, said it was fortunate the fire happened before the early morning prayer when there weren't as many people at the mosque.

"God bless that it didn’t happen that way,” he said.

There was visible scorching to one of the mosque's exterior walls, Lick said. It appeared that the fire’s damage was contained to this area of the mosque, located at 318 W. Sixth Ave.

Dar-ul-Arqam was built four years ago and serves a community of several hundred people in Escondido, Miller told NBC 7.

He said the tension is high following the fatal shooting in New Zealand.

“We’re not surprised by this incident," Miller said. "But, we’re very on edge right now.”

Seven people were inside the mosque for religious purposes at the time of the fire, police said. They were able to put out the fire with a fire extinguisher before firefighters arrived on the scene.

“There are people who sleep there overnight,” Miller said. “They heard the sounds, they smelled some funny smells, and there was a letter saying something connecting to New Zealand at the same time. So, this made everybody especially on edge.”

Police said the suspect left a message in graffiti in the mosque’s parking lot. EPD did not reveal what the graffiti said, only noting that it referenced the New Zealand shooting.

“Everybody should stay absolutely vigilant and watchful over their prayer centers. If there are people in the neighbor that are not supposed to be there, please give us a call,” Lick said. “We have also just re-doubled our efforts in terms of making sure that there’s a high police presence in the area.”

Anyone with information may call the EPD’s Community Safety Tip Line at (760) 743-8477.

The stretch of West Sixth Avenue in front of the mosque was closed for a time while officials investigate; however, Miller said it won't stop the mosque from remaining open as a place of worship.
