A few errant fireworks qucikly turned into a much bigger problem Saturday night for the Riverside man who shot them off, Buffalo police said.

Police said Donald Isch, of Condon Street, blew off fireworks “and lied to police about it,” the report said, when the explosives caused his garage to catch on hire.

After searching Isch’s home, police said they found a marijuana growing operation in two rooms on the third floor of the home.

Narcotics detectives were called and the plants were seized as evidence. Isch faces charges of arson and drug possession, police said.
