Police are appealing for information after a wheelchair-bound man was targeted in a robbery in Lancing.
At around 8.45pm on Thursday, the victim, a man in his 50s, was at his home in Sompting Road when he received a knock on his front door.
When he answered it, he found a man claiming to be an undercover police officer, who said he needed access to the property.
The victim didn’t believe the man and told him to leave.
Another man then appeared at the door and then entered the property, knocked the victim out of his wheelchair and stole his mobile phone.
They then left and the victim called for assistance from a neighbour.
The victim hit his head during the incident and as a result suffered a small cut.
Officers investigating the incident are considering whether this incident is linked to two similar offences, which happened in Cokeham Lane, Sompting and Sompting Road, Lancing, earlier this month.
Detective Sergeant Kevin Scullion, of West Sussex CID, said: “These incidents were extremely distressing for the victims and we are working to establish who carried out these robberies.
“The callers are both described as in their late teens and I would appeal for anyone who has seen anyone suspicious in the area in the last few days, or received a similar call recently, to contact us.
“Police officers will never ask for access to your property without providing identification. We would encourage everyone to use a security chain when opening the door, especially if you are not expecting a caller and if in any doubt about the identity of someone ask them to wait and contact the company they claim to be from using a phone book to find the telephone number.
“If you are concerned about these incidents then please call Sussex Police on 101 and ask to speak to your local PCSO who will be able to give you further advice.”
Anyone with information regarding these incidents is asked to contact Sussex Police on 101 quoting serial 1582 of 28/11 or the independent charity Crimestoppers anonymously on 0800 555 111.
