Four men arrested on suspicion of murdering a man outside his home in India have been released without charge, police said.
Rulda Singh, described by police as a “high profile public figure”, died two weeks after being shot outside his home in Patiala in the Punjab state of India, in July 2009.
West Midlands Police said today two men aged between 27 and 37 from Smethwick, Wolverhampton, and two from Coventry were originally detained in July last year.
They have now been released from police bail without charge.
The investigation – led by the West Midlands Counter Terrorism Unit – was continuing, a spokeswoman said.
Detective Superintendent George Tracey said: “This is a complex international investigation.
“Our inquiries are ongoing and we remain in close contact with the Indian authorities.”
