THE woman arrested by anti-terror police investigating the London and Glasgow bomb plots has been released without charge.

Marwa Asha, 27, was arrested with her husband, Dr Mohammed Asha, 26, of Newcastle-under-Lyme, Staffordshire, on the M6 motorway in Cheshire on June 30.

A Scotland Yard spokesman she was released at about 7.40pm yesterday.

Police are continuing to question four men who are being held at London’s high-security Paddington Green police station.

Two are trainee doctors, aged 25 and 28, who were arrested at the Royal Alexandra Hospital, Paisley.

A 26-year-old doctor from Bangalore, India, who worked at Halton Hospital in Runcorn, Cheshire, was arrested in the Lime Street area of Liverpool on June 30.

Also under police guard is a man arrested after a flaming Jeep was driven at Glasgow Airport.

He is being treated for burns and is in a critical condition in hospital.

On Saturday, an Iraqi doctor became the first person to appear in court charged in connection with the suspected car bomb plots in London and Glasgow.

Bilal Abdullah was remanded in custody when he appeared at City of Westminster Magistrates Court in London.

The 27-year-old, who was arrested after the Glasgow Airport incident, is accused of conspiring to cause explosions.

Meanwhile, it has been revealed that staff flats at Inverclyde Royal Hospital in Greenock have been sealed off and searched over the last few days by police investigating the plots.

A number of items were reportedly removed from one of the premises during the searches, which began on Tuesday.

And meanwhile in Australia, police have dropped a request to extend the detention of a suspect in the failed British terror attacks.

But despite the move, he was not likely to be released immediately and could still be charged.

Australian Federal Police withdrew their application to a magistrate to extend the detention of Indian doctor Muhammad Haneef beyond Friday under counterterrorism laws.

The move meant that police had 12 hours left to question Haneef before either charging him or releasing him.

Under the laws, the clock runs only when police are actively interviewing Haneef - meaning that with breaks, the deadline could be further off in real time.

Haneef, 27, who went to Australia from Britain last year, was arrested on July 2 as he tried to leave the eastern Australian city of Brisbane for India on a one-way ticket.

Police are investigating links between Haneef and some of the seven suspects held in connection with the attempted attacks.
