Miscreants hurled explosive substances at Teynampet Police Station on Thursday morning.
Initial reports said a few drunkards have thrown bottles filled with kerosene on the vehicles parked inside the police station at early morning. While police personnel tried to nab the miscreants, they escaped in two wheelers.
No one was injured and no vehicle was damaged due to the incident as the bottles did not detonate.
City Police Commissioner A.K.Viswanathan visited the spot and held enquiry. However, police downplayed the occurrence as a minor incident due to an enmity between two groups who were living behind the police station.
Further investigation is on.
