A MUM was horrified after finding two obscene video messages on a new mobile phone she bought for her 12-year-old son.

Martine Greenwood, 43, of Canvey, visited the Tesco Extra supermarket, in Maldon, to buy two new mobile phones – one for herself and one for her son, Aaron.

Mrs Greenwood spent £60 on two 02 touch screen pay-as-you-go phones, which were tested in the shop by a salesman.

However, when she got home the mother found lewd material on one of the mobiles.

She said: “I turned on the phone, and started to play around with it, when suddenly I saw two pornographic video clips.

“One had a woman running around with no top on, and the other was of a cuddly children’s toy hamster, swearing and using profane language.

“I just couldn’t believe it. What if my son had got to the phone first?

“I’m worried someone else will buy the same make and model and they will find the disgusting content.

“They need to sort this out and carry out better checks before selling equipment like this. Customers shouldn’t have to find this sort of thing on their phones.”

Mrs Greenwood has since visited the store to get a replacement phone.

A Tesco spokesman said: “We apologise to the customer for any distress caused by this incident.

“We will be investigating this matter thoroughly and will be in touch with the customer.”
