Child sex charges against a detective involved in the inquiry into murdered schoolgirls Holly Wells and Jessica Chapman have been dropped.
Detective Constable Brian Stevens had been charged with indecent assault and possession and distribution of indecent images of children.
The charges were dropped at Snaresbrook Crown Court in London today after new information came to light.
"In the light of additional information recently received by the Crown Prosecution Service (CPS), the allegations...against Brian Stevens have been carefully re-considered," the CPS said in a statement.
"Following this process, it has been decided that there is no longer a realistic prospect of conviction in relation to these charges and no evidence has been offered."
Stevens' lawyer, Alasdair Carnegie, said the policeman was pleased with the outcome.
"Detective Constable Brian Stevens is delighted the Crown has offered no evidence against him. Since his arrest in September last year he has protested his innocence and his acquittal today confirms it," Carnegie said.
Cambridgeshire police said Stevens would continue to be suspended from duty until all matters had been resolved.
Stevens had provided personal support to Jessica Chapman's family and read a poem at her memorial service.
The 10-year-old girls disappeared from Soham in Cambridgeshire on August 4 last year. Their bodies were found in a ditch 13 days later after a huge police search.
In March, former PC Anthony Goodridge, who also worked on the Soham inquiry, was jailed for six months after pleading guilty to possessing 330 indecent photographs of children.
Ian Huntley, a former school caretaker, has been charged with the murders and is due to stand trial in October.
