An apparent jewellery heist in Mexico involving a young child has been captured on CCTV.

In shop security footage a woman, who appeared to be the child's mother, distracted shop staff while the boy removed several items from display cabinets.

The woman then told the employees that her car was illegally parked and the pair quickly left the shop in Oaxaca that specialises in silver products.

Twenty minutes later, the clerks noticed over £250 worth of merchandise missing.

Saleswoman Ana Lilia Hernandez said they did not suspect the woman and child until the store owner saw the theft on the store's security video.

"After about 20 minutes, we realised that the piece (of jewellery) was missing, that it wasn't in the cabinet that we have in front which was open. But we were never suspected the boy and the lady because the lady came with a boy who was a bit naughty but that was it, he was walking back and forth but we never suspected it was that customer," she said.

The store owner reported the crime but police have yet to make an arrest in the case.
