A mother says she fears for the safety of her son who has been locked up in a Spanish jail for nine weeks.
Paul Brewster was arrested on 28 March in Spain
Paul Brewster, 31, from Whitley Bay, North Tyneside, was arrested in Malaga in 28 March and has been in a high security prison awaiting trial.
Mr Brewster, who suffers from mental health problems, is accused of robbery with violence, but admits only throwing a single punch at another man.
His mother Elizabeth says British officials have not helped enough.
Mrs Brewster said: "Paul is absolutely ill, he just cannot cope. His depression is becoming worse because he is locked up in a jail in Spain, where no-one speaks English.
"I've been trying to help for over a month and no-one seems to take responsibility.
"Paul can't speak Spanish. I saw him on Saturday night after waiting for a week. No-one told me what to do or where to go. No-one spoke English and I felt like a convict myself."
Mrs Brewster said she was becoming concerned because her son had talked about suicide.
She has been given assurances that a Spanish doctor is supervising her son's medication, but she has urged the Foreign Office to press for her son to be moved from the high security prison near Granada.
In a statement the Foreign Office said: "We are aware of the case and have been providing consular support to Paul and his family in the UK following his arrest.
"Our prime concern is the welfare of British nationals overseas and our consular staff in Granada have visited Paul whilst he has been in prison.
"We have been in touch with Paul's UK-based mental health worker in order to get a detailed report on his condition and have passed this information onto the prison doctor.
"We are not able to intervene in the criminal court proceedings involving Paul as it is a matter for the Spanish authorities."
