The Centre proposes to make production of Photo identity card mandatory for purchase of acid. In an affidavit filed before the Supreme Court on Tuesday, the government listed a number of measures to curb the sale of acid in the open market.

The shopkeepers will also require licence to sell the acid. The move comes after Supreme Court asked the government to submit guidelines to check open sale of acid, thereby checking acid attacks on women.

It is estimated that one thousand acid attacks take place in India every year. The apex court order came on a PIL seeking framing of a new law or amendment in the existing laws to deal with acid attack effectively.
