A Scot who allegedly had his genitals electrocuted while being tortured is reportedly back in police custody - just hours after he was moved to a jail until the end of the month.

Jagtar Singh Johal, who has lived in Dumbarton, West Dunbartonshire, for 15 years, was detained in police custody in Jalandhar in the state of Punjab on November 4.

The Sikh Federation UK said no official charges have yet appeared but local media reported Mr Johal's arrest was linked to the killing of Hindu leaders in Punjab.

Mr Johal is also said to have had his nipples and earlobes electrocuted during the ordeal.

He appeared in court on Friday and was remanded in jail until November 30.

But the Sikh Press Association - which is working with the family and the Sikh Federation UK - claimed he was moved back into police custody hours later.

The move came after officers went to the home of a judge and asked for the earlier decision to be reversed in light of new allegations against Mr Johal.

STV News understands he has not been given any fresh clothing.

Mr Johal's lawyers are said to have applied for an independent medical examination but it has been claimed their request has been denied.

Bhai Amrik Singh, chair of the Sikh Federation UK, said: "Many are asking why Jagtar was not allowed the business cards for his two lawyers or for the British High Commission representative or allowed to accept clothes from his family.

"The Indian authorities clearly have much to hide and the British and Scottish governments must do much more to secure his release.

"We will be challenging the Foreign Secretary next Tuesday when he appears in the Commons to answer questions from MPs."

Hundreds of Sikhs held a demonstration outside the Foreign and Commonwealth Office (FCO) in London on Thursday in support of Mr Johal.

The FCO said it has met Mr Johal and also met his family to update them, as well as confirming the 30-year-old had access to a lawyer.

A spokesman said: "Our consular staff in New Delhi have visited a British man who has been detained in Punjab.

"We have met his family to update them, and have confirmed that he now has access to his lawyer.

"We take all allegations or concerns of torture and mistreatment very seriously and will follow up with action as appropriate.

"When considering how to act, we will avoid any action that might put the individual in question or any other person that may be affected at risk."
