Police has charged a 48-year-old forklift truck driver for the murders of five prostitutes in Ispwich while releasing another suspect who was arrested.
Twice-married Steve Wright, who was arrested on Tuesday morning from his home in the red light area of Ipswich, has been charged for killing and dumping all five women in a murder spree, which shocked Britain.
He was questioned for just under three days over the death of Gemma Adams, Tania Nicol, three-months-pregnant Anneli Alderton, Paula Clennell and Annette Nicholls.
Tom Stephens, the 37-year-old supermarket worker who was arrested the day before Wright, was released on police bail.
The police officer leading the murder hunt Detective Chief Superintendent Stewart Gull told reporters that since the arrests there have been "significant ongoing inquiries and interviews during the period that these men have been in custody."
"As a result, the 37-year-old man was released on police bail, pending further inquiries. The second man, Steve Wright, from Ipswich, has been charged with the murder of all five women," he said.
Michael Crimp, senior prosecutor for Suffolk Crown Prosecution Service, said, "We will continue to keep this case under constant review as it develops."
More than 500 officers have been drafted in, many from around the country, to help the investigation. Police have sifted through more than 10,000 calls from the public and have viewed thousands of hours of CCTV footage.
