LARGO — Officers arrested a man Monday accused of throwing a Molotov cocktail into his ex-girlfriend's home, police said.

Samna Ngoun, 28, faces charges of first-degree arson, throwing a deadly missile into a building and violating a domestic violence injunction.

According to arrest affidavits, Ngoun shattered a window at his ex-girlfriend's Largo house on Feb. 23, then tried to throw the Molotov cocktail inside. However, it broke: The wick and some accelerant fell inside the house and the bottle remained outside, causing two small fires.

His ex-girlfriend and another person were home at the time.

During an interview with Largo detectives, Ngoun, of Pinellas Park, admitted to starting the fires because he saw his ex-girlfriend with another man, police said. He told detectives he "was only trying to scare her, not harm her," the affidavit shows.

Ngoun was booked into the Pinellas County Jail, where he remained Tuesday without bail.
