Police are still studying CCTV of two men who robbed a security guard delivering cash to a bank in Oxford.

The pair are believed to have stolen a “significant” amount of money as it was carried to the NatWest branch in Cowley Road at about 3pm on Tuesday.

They knocked the guard over and ripped a container he was carrying from his hand, injuring him.

The men are described as black, and about 6ft tall.

One was wearing a high-visibility jacket.

Call police on 101.
