The mother of Jay Slater, the British teenager missing in Tenerife, says she spent eight hours in a police station on Friday and believes police are “stepping up” their search.
Debbie Duncan told the Guardian she still thinks “something untoward” may have happened to her son.
She flew to the Spanish island on Tuesday, the day after the 19-year-old went missing, to help look for him.
On Saturday, the sixth day of the search, police, rescue dogs and firefighters reconvened at Rural de Teno Park, the last location logged by Mr Slater’s phone.
Ms Duncan told the Guardian police have said the “noise” around the case was affecting their investigation.
It comes after reports somebody logged into Mr Slater‘s Instagram account who was not him.
Rachel Louise Harg set up a GoFundMe page to go towards search efforts and a Facebook page to help find him.
She said people who had been “hacking” the social media accounts of Mr Slater’s family were “sick in the head”.

Ms Duncan said police had told her they were “investigating all leads”.
“They’ve got all the plans, their locations,” she added.
“They have got this map they were showing us, shaded different colours.”
She renewed calls for British police to help with the search, saying there had been a “problem with the language barrier”.
But Spanish police have rejected an offer by Lancashire Constabulary to assist. The force said while the case “falls outside the jurisdiction of UK policing”, it offered to support Spanish police “if they need any additional resources”.
The force added: “They have confirmed that at this time they are satisfied that they have the resources they need, but that offer remains open and they will contact us should that position change.”
Mr Slater is from the Lancashire town of Oswaldtwistle, where specialist officers are continuing to support his family, the force said.

The apprentice bricklayer was holidaying with friends on Tenerife before he disappeared, and had been at the NRG music festival on Sunday.
He was last heard from just after 8am on Monday, when he called his friend Lucy Law to say he was setting off on an 11-hour walk to get home after missing a bus.
She said he told her he was lost, in need of water, and only had 1% charge on his phone.
