Atiq Ahmed, a Lok Sabha member from Phoolpur in Allahabad, who was evading arrest for the past six months in the murder case of a legislator in Uttar Pradesh was arrested by the police in Delhi.

Ahmed, an expelled Samajwadi Party member of Parliament, was arrested by special cell of Delhi police on Thursday evening from a apartment in Preetampura in west Delhi, a senior police official said on Friday.

He was on the run after his name cropped up in the sensational murder case of Raju Pal, a Bahujan Samaj Party MLA in UP. He carries a reward of Rs 20,000.

The Uttar Pradesh police has secured a non-bailable warrant against him in connection with the Pal murder case.

Ahmed had alleged that there was threat to his life from Uttar Pradesh Chief Minister Mayawati and it was for this reason that he was not surrendering to the state police.

Earlier, Mayawati had accused Congress leaders of conspiring to eliminate her and claimed they were "patronising" Ahmed whom she dubbed as "mafia".

A number of cases including that of murder, attempt to murder and kidnapping were registered against him.
