Two families in San Diego’s Southcrest neighborhood say they were targeted by someone throwing homemade firebombs.

Police are asking that the public help identify people seen on video throwing bottles at a home, causing explosions.

The suspect first threw a Molotov cocktail at the home shortly after midnight, which failed to ignite and went unreported, police said. When the suspect returned around 2 a.m. and threw a second Molotov cocktail, the resident, who is a legal gun owner, fired several shots at the suspect and called police. The suspect was not hit, police said.

Investigators are looking into an incident in Southcrest in which what are believed to be Molotov cocktails were thrown at a home.
