A 23-year-old man has been arrested on suspicion of conspiracy to murder.
It follows an incident where a man riding a motorcycle fired a number of shots at a black BMW in Fountains Road, Luton, last month.
A 23-year-old was arrested by Bedfordshire Police after a warrant was executed in Littlefield Road on June 4th. He has been released on police bail pending further enquiries.
A further 23-year-old Luton man has already been charged with attempted murder and one count of possession of a Section One firearm in connection with this incident.
