Hurt by allegations of harassment of members of Muslim community during the ongoing probe of July 11 serial blasts, Mumbai police chief A N Roy has written to prominent members of the community, clarifying that the police holds no bias against them.

Roy has sent a letter to nearly 100 religious and social personalities from the community, clarifying the situation developed in the aftermath of July 11 blasts, and why people were summoned for questioning.

Written in Urdu, the letter states that the police have a mammoth task of reaching the culprits who meticulously planned the blasts, killing over 200 persons and injuring more than 800.

Several people were called for questioning on the basis of information received by police, Roy has said.

'Yet, there is no bias against any community or group. Terrorists have no religion and are working against humanity. Our investigation is trying to ensure that there is no bias against anybody', Roy has said, urging the community members to contact him in case they notice any incidence of a bias.

'Officers found guilty in such incidents will be punished', he has said.

The Mumbai police chief has also said that at times the media too paints a wrong picture.

The clarification has come after a section of the minority community alleged that Muslims who have recently gone abroad or plan to go, were being harassed by police.

Bollywood choreographer Raju Khan was one such person who raised his voice after police asked him to provide details of his recent foreign visit.
