The victim stepped out of a train at around 9.40pm on Monday evening when he was approached by another man who distracted him by dancing.

The victim soon discovered that his necklace had gone missing. The culprit is said to belong to a group of four men who were in the same train carriage as the victim. They appeared to be between the ages of 20 and 25 and were all carrying backpacks and wearing black jackets.

The police have opened an investigation into the incident.
