Two more men have been arrested by detectives investigating a series of rapes in Northampton.
Three rapes are being investigated in the town
A 36-year-old man from Northampton was arrested on Wednesday night and is being held on suspicion of rape.
On Thursday a 19-year-old man from Northampton and a 25-year-old man from London were both arrested on suspicion of attempted abduction.
Between 31 July and 8 August three women were raped and attempts were made to abduct two other women.
Police said they were keen to find two cars, a BMW and Fiat Punto, used by the men involved in the attacks.
During the latest incident on 8 August a 30-year-old woman was raped in Exeter Place.
Forced into car
Earlier, an attempt was made to abduct a 15-year-old girl as she was walking near the back of the hotel complex Sol Central in the early hours of 1 August.
Less than an hour later an 18-year-old walking in Horsemarket Street in the town centre was forced into a car, driven to the village of Duston and raped.
After police released details of these attacks, an 18-year-old woman revealed she had been raped on 31 July on a side road near Marefair.
On 3 August a 25-year-old woman ran into Northampton Hospital to escape from a man who said he wanted to give her a lift home.
Police received more than 2,000 calls after making a public appeal.
Since the attacks police have almost doubled the number of officers on patrol in the town and there has been an increase in demand for personal attack alarms in Northampton.
Last week an anonymous donor offered a £500 reward for information leading to the capture of the men, and this figure was matched by Northamptonshire Police.
On Tuesday police said they were closing in on the men, and appealed to the attackers' friends and family to come forward.
