NORWALK - Many Norwalk residents are concerned about gang activity after several recent incidents.

The latest occurred when gunfire erupted on School Street at around 11 p.m. last night, police say.

Investigators say the incident came just three days after someone in an SUV fired at least five shots into a home at 71 Saddle Road. No one was injured.

Neighbors say they believe both shootings were the result of gangs claiming new turf. Police, however, have yet to determine if either incident is gang-related.
