A woman was robbed at knifepoint as she walked through South Park, Oxford, yesterday morning.

She was approached from behind as she walked down the hill, near the horseshoe of trees, at about11.30am.

The mugger took the woman to a wooded area where he made her hand over money, before she ran off.

Dc Lucinda Bevan, of Oxford CID, said: "This attack happened in broad daylight in a popular spot and other park users may well have seen this robbery take place but not realised what was going on."

The robber was a black man, aged 18 to 30, about 6ft tall and of average build. He was wearing a dark hooded top or jacket.

Anyone with information should call Dc Bevan on 08458 505505 or the anonymous Crimestoppers hotline on 0800 555 111.
