An unidentified man robbed a 75-year-old woman of her gold jewellery at knifepoint on Wednesday.

Police sources said Ambujam was alone at her residence on 20 Street, N Block in Anna Nagar East when two men on a motorcycle stopped nearby. One of them asked her for a glass of water. When she went inside the house to bring it, he went after her and threatened her at knifepoint.

In spite of her cries for help, the man managed to snatch a gold chain and bangle that she was wearing and fled on the waiting motorcycle ridden by his accomplice, sources added.
