The main accused in the Malwani (Mumbai) hooch tragedy was arrested in Delhi on Tuesday. 

At least 102 people have died and 46 others are undergoing treatment after drinking the illegally-made toxic country liquor allegedly smuggled into Mumbai from Thane, where it is manufactured.

The victims were residents of Laxmi Nagar slum in Malwani in suburban Malad. They had consumed the toxic liquor on Wednesday evening and their health started deteriorating at night.

The Mumbai police crime branch have so far arrested 20 people. They are on the lookout for three more, believed to be kingpins of the Mumbai hooch racket.

Of the three, one is Akka, the woman who allegedly supplied the toxic liquor to the slum dwellers.

This is the worst hooch tragedy in 11 years in Maharashtra. In 2004, about 87 people were killed after consuming spurious liquor.
