LUCKNOW: UP police on Monday wrote a letter to Twitter Inc asking for removal of certain photographs and text uploaded on the social networking service said to be related to the Dadri incident in which Akhlaq (50) was lynched following rumours that his family had consumed and stored beef.

IG (administration) Prakash D said the letter was sent by the social media lab of UP police asking for removal of specific photographs and text uploaded by a twitter handle. "We are investigating into the other aspects like the individual behind the handle that was used to upload this objectionable text and graphics as such activities whip up communal passions which can prove detrimental for the surcharged atmosphere prevailing in certain parts of the state," he said.
