A man has been convicted of making hoax bomb threats to Croydon's Lunar House office block - on the day after the Manchester Arena terror attack.

Ahmed Belkasim, 30, phoned the immigration compliance and enforcement team, which is based at Lunar House, a total of five times on May 24, saying: “I don’t know how to make bombs, but I’m going to come and bomb you.”

The following day he phoned five more times and made reference to the Manchester attack, adding: “Twenty-two dead - there will be more than that when I’m finished with you.”

Belkasim, of Dowell's Street, in Greenwich, denied making the calls and blamed others, even after a recording of the conversation was played to him.

His voice was recognised by the call centre worker as a regular caller however and he pleaded guilty at the Old Bailey yesterday (November 14).

Crown prosecutor Daren Streeter said: “Ahmed Belkasim used the terrorist atrocity in Manchester in an attempt to strike fear into a Home Office employee.

“Our prosecution proved Belkasim intended to cause alarm and our case against him included call recordings, witness statements and comments made as he was arrested.

“No-one should have to be caused alarm in this way and the CPS will prosecute anyone who makes these kind of threats.”

Belkasim will be sentenced on December 5.
