Two Pakistani policemen have joined the investigation into Bob Woolmer's murder as Jamaican police were not able to make any breakthrough even three weeks after the coach's mysterious death.
Pakistani sleuths -- Mir Zubair Mahmood and Kaleem Imam -- joined four Scotland Yard investigators and two forensics experts from Interpol, the France-based international police agency, who have been aiding in the probe into the death of Woolmer.
The Pakistani police have arrived in Kingston in a bid to accelerate the investigation, said Gilbert Scott, Permanent Secretary in Jamaica's Ministry of National Security.
"They will be here for as long as it takes," Scott was quoted as saying in the media in Kingston.
Mark Shields, Jamaica's deputy police commissioner, said the Pakistani investigators would help with DNA analysis and would examine theories that Woolmer, Pakistan's coach since 2004, may have been poisoned before he was strangled while authorities are still awaiting toxicology reports.
The 58-year-old Woolmer died on March 18, a day after his side had been shocked by Ireland and knocked out of the cricket World Cup.
