A Florida man was arrested Friday for allegedly plotting a mass shooting at the Islamic Center of Northeast Jacksonville, authorities announced Monday.

The Florida Department of Law Enforcement, the Jacksonville Sheriff's Office and the FBI began investigating the suspect, identified as 69-year-old Bernandino Gawala Bolatete, in October, when they received a tip that he allegedly planned to open fire at the Islamic Center, reported WJXT, a Fox affiliate in Jacksonville.

An undercover officer then communicated with and recorded Bolatete, confirming his plans to carry out an attack with a firearm, Sheriff Mike Williams said at a press conference.

"The investigation confirmed that the suspect was making plans to carry out a mass shooting and already had the weaponry necessary to complete the attack," said Williams.

During the investigation, the FBI also learned that Bolatete intended to have an unregistered silencer delivered to his home Friday. According to police records, the undercover officer helped him purchase the attachment for $100.

At the time of the delivery, a SWAT Unit from Jacksonville Sheriff’s Office stormed Bolatete’s home, where he was arrested and later transferred to FBI custody. Court documents show that Bolatete hadn’t planned to survive the shooting, instead citing a "suicide by cops."

Bolatete was charged with the illegal possession of a firearm silencer, while other charges are currently pending. If convicted, he’ll be sentenced to 10 years in federal prison. He has a green card and is from the Philippines, according to the FBI.

Bolatete’s investigation is ongoing and he could face additional charges.
