In the aftermath of the acid attack on a teenager and her mother by a youth near Pettai here on Wednesday, the police conducted nocturnal raids on shops selling chemicals and acid across the city. Twelve unauthorised outlets were sealed.

K.Sundar, a 26-year-old youth who was upset over his father’s second marriage, went over to the residence of Chellakutti, at Thiruppanikarisalkulam near Pettai, who is said to have solemnised the marriage.

In the course of an argument with Chellakutti’s wife Chidambaram, Sundar hurled acid on the woman and her 19-year-old daughter Seetha. Sundar was later arrested.

Police sources said the raid led to the seizure of 990 litres of sulphuric acid, 137 litres of nitric acid and 33 litres of hydrochloric acid, for which the shopkeepers could not produce proper receipts.

Commissioner of Police Mahesh Kumar Aggarwal told reporters that cases had been registered against the shop owners. “Suresh, a shop owner, has been arrested,” Mr.Aggarwal added.
