One of the two Ukrainians arrested in relation to bomb attacks in England, is also suspected of murdering Birmingham pensioner Mohammed Saleem, the press service of West Midlands Police reported on Saturday.

"The murder of Mohammed Saleem now forms part of the wider West Midlands Counter Terrorism Unit Investigation," reads a press release posted on the police's Web site.

"A 25 year old man from Ukraine remains in custody today (Sunday) as part of the ongoing counter terrorism investigation into explosions near mosques in Walsall, Tipton and Wolverhampton," the police said.

Mohammed Saleem, 75, was stabbed to death not far from his home in Small Heath, Birmingham, on April 29 when he was returning from an evening prayer in a local mosque, Birmingham mail reported.

West Midlands Police reported on July 19 that two Ukrainian men, aged 25 and 22, were arrested in Small Heath on July 18 and are suspected of involvement in explosions near mosques in Walsall, Tipton and Wolverhampton.

On July 20, Westminster Magistrates Court extended the detention of the two men which gives police officers seven days to question the Ukrainians.

The Independent reported on July 20, that anti-terrorist officers searched on July 18 the headquarters of software company Delcam where the two men were on work placements. Chief executive Clive Martell, who was at the factory, said one of the men, both engineering students in Eastern Europe, had been at the company for four months, the other for two.

"The two men were on work placements with us, but were not employees of the business. They were around halfway through the course and we understand that they met each other whilst on the placement," he said.

The Foreign Ministry of Ukraine has neither confirmed, nor refuted the information.

Remnants of a homemade explosive device were found outside a mosque in Walsall on June 22 when police were called to reports of a suspicious item at the Aisha mosque.

Officers were called to wasteland off Binfield Road in Tipton July 12 following residents reporting a loud bang, which resulted in scattered debris, including nails. No one was hurt in the explosion.

"Following the arrest of two men on July 18 an area in Wolverhampton was evacuated and searched near to the Wolverhampton Central Mosque on Waterloo Road. A seat of an explosion and debris was subsequently found. Whilst the investigation is in its very early stages, early indications are that the explosion happened June 28," West Midlands Police said.
