Four West Midlands men arrested over Punjab murder case
Four men have been arrested in the West Midlands on suspicion of murdering a man in the Punjab area of India.
Rulda Singh died after being shot outside his home in Patalia in 2009. Two men in the state of Punjab have already been charged with his murder.
Police arrested two men in Coventry earlier while two more were arrested at their homes in Smethwick and Wolverhampton.
They are all British nationals and aged between 27 and 36.
Mr Singh, who was in his 60s, was the head of a Sikh socialist organisation.
West Midlands Police said the case was being handled by the Counter Terrorism Unit (CTU) because the case had potential links to Sikh extremism.
Detectives travelled to India to conduct initial investigations in April.
Det Supt George Tracey, from the CTU, said: "We have been working closely with the Indian authorities on this matter.
"The investigation into the death of Mr Singh is complex and ongoing both here and in the Punjab."
