A thief snatched a Rolex from the wrist of a 91-year-old man.

The pensioner suffered a minor wrist injury during the incident in Fitzalan Road, Littlehampton, at 2.30pm on Friday.

"We have increased our patrols in the area and if anyone has concerns please speak to one of our officers."

Anyone who witnessed the incident is asked to report any information they may have online or ring 101 quoting serial 694 of 12/02.
