The Nolambur police have apprehended two persons, including a juvenile, who were part of a gang allegedly involved in hurling a country-made bomb at a house in Mogappair early on Thursday.

According to the police, the incident was a fallout of a skirmish that broke out when the residents questioned the gang for consuming alcohol and smoking ganja on a vacant plot near the house and creating nuisance.

Police sources said the complainant heard a loud explosion from the rear side of their house.

Manivannan and Manimaran, both ambulance drivers resided on Venugopal Street in Mogappair. At around 1 a.m., something like a loud explosion was heard from the rear of their house.

Alarmed, they rushed out of the bedroom to find the rear roof of the house and window panes shattered. The wall had developed cracks due to the blast.
