We are appealing for information from witnesses who may have seen three men acting suspiciously in Sunbury-on-Thames on Monday afternoon (1 July).
The men, who were going door to door, are believed to be responsible for an aggravated burglary which left the occupant with facial injuries. Personal property, including a wedding ring, was also taken.
We are also looking for a silver BMW X3 or X5 in connection with this incident.
The three suspects are described as having Eastern European accents, with one wearing a suit and gloves, while the other two were wearing casual clothing.
If you saw anyone matching the descriptions going door to door or in a silver BMW, please get in touch with us straightaway on 101, quoting crime reference number PR/45190068517. If you do not wish to leave your name, call the independent charity Crimestoppers on 0800 555 111.
