A HALLOWEEN style plastic arm sparked a major police operation off the M62, disrupting thousands of motorists. The drama, complete with a helicopter and police dogs, was caused by a joke shop forearm with fake blood. Today police said it may have even fallen from a passing lorry or car. The saga began when members of the public reported seeing a severed arm lying on an exit sliproad, prompting police to scramble the force helicopter. The slip road approaching Tarbock island at junction 6 was shut down for several hours while scientific support officers scoured the verge with police dogs while the chopper roared over head. Initial reports suggested the police were hunting for a city villain, but by late afternoon rumours began to circulate that a severed arm was the cause of the incident. Eyewitnesses at the scene reported chaos as members of the public wandered around in the road and police cars lined up at the traffic island. More
