Two more men were arrested today in connection with the drive-by killing of 14-year-old Danielle Beccan in Nottingham.
The men, from Nottingham, were arrested in the city early this morning.
The move comes as officers continue to question a man arrested in London on Monday night. Four others detained with him were released without charge yesterday.
Danielle was shot dead yards from her home in the St Ann's area of Nottingham on Saturday.
She was returning from the city's annual Goose Fair with a group of friends when she was hit by one of several shots fired from a passing gold-coloured car.
Nottingham detectives said they are unable to explain why Danielle, or her friends, might have been targeted by gunmen and fear she was the victim of a random attack.
