A suspected serial killer was under arrest yesterday in connection with a spate of murders in Parisian housing estates after detectives identified a motorbike driven to the crime scenes.

Four people were shot dead in five months all with the same type of semi-automatic weapon by a gunman who fled on a motorbike. Police are holding a 33 year-old of West Indian origin known only as Yoni P. who they describe as a "very serious" suspect in relation to three of the four murders.
