Jay Slater's Instagram 'accessed multiple times' since going missing as friends issue warning

With the search for the 19-year-old entering its sixth day police efforts to find the boy have been stepped up by Spanish police.

The Civil Guard, mountain rescue teams and various other emergency services are all involved with the search. Helicopters, rescue dogs and drones have all been deployed in a bid to find Slater.

While family and friends desperate for any information that may help locate Slater, a warning has been issued on an official Facebook page being used to provide updates on the search.

In a post, a family friend wrote: "Jay's mums asked I post this.

"For everyone asking who has logged into his instagram account, it’s not him or her, somebody else has logged into it."

The update suggests that hackers of bots have been targeting the account since Monday.

Slater's mum, Debbie Duncan, and others close to him have been subjected to a series of horrific messages on social media over the past six days.

Earlier this week Duncan explained that in one vile message she had received on Snapchat someone told her she would never see her son again.

The sick message read: “Kiss goodbye to your boy, you’re never going to see him again, he owes me a lot of money.”

Her eldest son Zac managed to screenshot the message before it disappeared, and she quickly alerted the police.

Last night Duncan said police had told her "noise" on social media was impacting their investigation.

"We've been there [the police station] all day today, and I think it's been stepped up," she said.

"We've had a problem with the language barrier. It's difficult with all the Spanish police and British police; they have to let the Spanish police do the investigation.

"They have actually said that there's too much noise - that's affecting it.

"They've got all the plans, their locations. They have got this map they were showing us, all shaded in different colours."
