RELATIVES of a couple missing in Tunisia have taken to social media in a bid to find them.

Samuel Stocker, from Crawley, took to Twitter to try and find his grandparents John and Janet Stocker in a campaign which has been shared more than one thousand times.

He has posted pictures of the couple on Twitter as their relatives desperately hear for news.

Mr Stocker has started a Twitter hashtag, #FindJohnAndJanetStocker as part of the appeal.

He is among many relatives and friends of British tourists who are missing after the massacre who are appealing for information on social media as the agonising wait for victims to be officially named continues.

Islamic State extremist militants have claimed responsibility for the attack, which happened in Sousse on Friday.

Tunisia’s Prime Minister Habib Essid has said UK had suffered most fatalities after a gunman opened fire on holidaymakers sunbathing on a beach.

At least 38 people including 15 Britons were killed in the massacre.
