Mr Masroor wrote on his Facebook page that he was visited by police officers from Scotland Yard this week after he had put his children to bed. Imam and broadcaster Ajmal Masroor was one of the figures threatened in the video. He wrote this post on Facebook He said he was told his life was in danger when they showed him a piece of paper. The basic message contained in the paragraph was that my life was in imminent danger from the terrorists. The police officers were visiting me to give me a warning and asking me to be more vigilant. They were being the messengers. They left me a telephone number to call in case of emergency or if I felt under any immediate danger. They did not give me any further details and left me guessing. As soon as they left my house I started digging further and found an Al-Shabab video has been uploaded on the Internet and in it they name me as a Muslim who is an enemy of Islam and should be eliminated. They name a few others in their video message and encourage people to resort to using knives to behead people like me. I spend some time today to verify the threat and it was confirmed to me that it was this video that had spurred our security services to action. The video is thought to have been filmed before last month's massacre at a Kenya mall which left at least 67 people dead. Scotland Yard told the MailOnline: 'We are aware of the video that has been released and we are currently assessing it's contents.'
