Fire investigators Wednesday released video surveillance footage in hopes of identifying an arsonist who set fire to a leasing office in an El Toro apartment complex, causing more than $100,000 in damage to the building.

The footage captured the suspect pouring a liquid on the outside of the building on El Toro Road and then setting fire to it in the early morning hours on Tuesday, according to the Orange County Fire Authority.

An arsonist is caught on video setting fire to a leasing office in Lake Forest. Vikki Vargas reported on NBC4 News at 4 p.m. on Wednesday, Jan. 15, 2020.

An OCFA accelerant detection dog, Freedom, was brought to the scene with his handler and was able to identify areas that contained an accelerant, according to Capt. Tony Bommarito.

"This arson fire was started just 50 feet away from occupied apartments," according to an OCFA statement. "This appears to be a targeted attack by someone familiar with the area. Investigators need the public's help identifying this arsonist before he strikes again."

Anyone with information was asked to call investigators at 714-573-6709.
