A Delhi court on Thursday issued a production warrant against underworld don Abu Salem [Images] as the Mumbai police failed to produce him before it in connection with a case of allegedly attempting to extort Rs 5 crore from a contractor in Delhi.

Additional Sessions Judge Ravinder Kaur directed the Arthur Road Jail authorities to ensure Salem's presence on August 21.

Salem, who was brought to Delhi from Mumbai in connection with another extortion case, was declared a proclaimed offender in the case in which five of his alleged syndicate members, including a woman, were arrested for threatening Ashok Gupta, a south Delhi contractor.

The court had allowed the special cell of the Delhi police to quiz him after it moved an application about the case registered under the Maharashtra Control of Organised Crimes Act against the gangster and his associates.

The police has already filed a chargesheet against the other five accused -- Pawan Kumar Mittal alias Raja Bhai, Sajjan Soni alias Babu Bhai, Majid Khan alias Raju Bhai, Mohammed Ashraf alias Babloo and a woman Chanchal Mehta.

According to the police, the don, in the year 2002, had made threat calls to contractor Ashok Gupta, a resident of Greater Kailash in south Delhi, demanding Rs 5 crore as protection money.

Salem, who is facing trial in eight cases in India, was lodged in Mumbai's Arthur Road Jail after his extradition from Portugal in 2005.
