A Delhi court on Friday extended by eight days the custodial interrogation of Saigal Hossain, former security guard of arrested TMC leader Anubrata Mondal, in a money laundering case related to alleged cattle smuggling.

Hossain, who allegedly amassed huge wealth through a cattle smuggling racket, was produced before the court on expiry of his six-day Enforcement Directorate (ED) custody granted earlier.
