Kent Police officers investigated after sex case inquiry
Two Kent Police detectives are being investigated and an inquiry is under way into concerns about the force's handling of a sex offence case.
The Independent Police Complaints Commission (IPCC) has informed both officers they are being investigated over allegations of gross misconduct.
It follows a trial this month, in which a man admitted several sex offences.
The watchdog said there had been a delay of nearly a year by Kent Police in taking a DNA sample.
'Two more attacks'
IPCC commissioner Mary Cuneen said the offender, a 46-year-old man, was identified as a potential suspect in autumn 2012.
She said the fact that a DNA sample was not taken from him until almost a year later was concerning.
"During the intervening period he carried out two more attacks on young women," she added.
Ms Cuneen said both victims had been informed of the IPCC's intervention.
She said the commission had to establish independently what actions were or should have been taken by police.
Investigators were also examining a delay in referring the matter to the IPCC, she added, because the force became aware of concerns in October 2013 but did not refer the case to the commission until 2 January.
The force issued a statement which said: "Kent Police strives to put victims first and is assisting the IPCC with its investigation.
"It would be inappropriate to comment any further at this stage."
