An abusive DVD featuring images of porn, worms, rats, skulls and the face of the Prophet Mohammed has been sent to several London mosques, and is now being probed by counter terrorism officers.
The highly offensive amateur footage, which is set to rock music, included footage from a BBC Newsnight investigation into banned Islamist group Al Muhajiroun.
The Qalb Centre, which supports vulnerable adults with drug and alcohol problems, received the DVD in the post at the time of the Muslim holiday of Eid, according to the Walthamstow Guardian.
Charity worker, Imran Mehtar, told the paper: “I didn’t get upset about it but it was very anti-Islamic and bigoted.”
He added that his non-Muslim colleagues had been "more upset by it".
“They said ‘why are stupid people sending this stuff to us? They need to get a life. It’s insulting to someone’s religion’.”
A Met Police spokesman told HuffPost UK: "Officers from Counter Terrorism Command are investigating a linked series of malicious communications in London and other parts of the UK.
"It follows a number of complaints to police from individuals and religious organisations that have received a DVD containing offensive material in the post. Inquiries are ongoing. There have been no arrests at this stage.
"Anyone who has been in receipt of one of these DVDs should contact their local police if they have not done so already."
The police are in possession of two of the DVDs, which are currently with forensic teams.
AbdulMaalik Tailor, community liaison officer for Anoor Mosque in Acton, west London, told the BBC's Asian Network they had also received the DVD, as had an organisation called Muslim History Walks.
"I didn't like it at all, initially it was just turned off, but then myself and other people at the mosque thought we have to see what exactly is in this film," he told the broadcaster.
"It's been heavily edited and put together. It wasn't pleasant at all - it's disgusting."
Outreach worker Mohammad Shakir also reported that the DVD was sent to the Muslim Media Forum and told the BBC he had reported it to the police.
He said: "It was shocking and offensive, especially as it was being watched in an office environment, and quite saddening that someone would take their time to create something like this."Suggest a correction
