The independent crime-fighting charity Crimestoppers and the Association of Convenience Stores (ACS) are offering a reward of up to £10,000 for information on a man responsible for a spate of robberies across Birmingham and the Black Country.

The area has seen a total of 12 robberies committed over an eight-month period between 30 March and 26 November at nine different supermarkets and convenience stores, taking place between 7.45pm to 10.30pm. One store was targeted on three separate occasions.

Each incident saw a man armed with a black handgun approach the tills, threaten staff and force them to hand over cash before escaping.

Now the charity Crimestoppers and ACS have offered a reward of up to £10,000 for information leading to the arrest and conviction of the person responsible.

Association of Convenience Stores chief executive James Lowman said: “Retailers are too often subjected to abuse and threatening behaviour as part of their jobs, which is absolutely unacceptable. We urge anyone with information about the people behind these crimes to come forward and talk to Crimestoppers.”

Roger Critchell, drector of operations for Crimestoppers, added: “Serial offenders like this need to be stopped before they create any more distress and fear to innocent shop workers in Birmingham.

“The fact this individual has threatened staff with a weapon indicates he does not care who he harms.”

If you have any information on this individual you can contact Crimestoppers anonymously on 0800 555111 or through the online form at www.crimestoppers-uk.org
