Police officers are to be interviewed following the conviction of a mentallyill man for stabbing a 24-year-old woman to death outside her home.

The Independent Police Complaints Commission will question officers and civilian staff from Warwickshire Police about the days leading up to the attack on Colette Lynch in Rugby.

Both Ms Lynch, from Garyth Williams Close, Overslade, Rugby, and Percy Wright, who last week admitted killing her, had contact with police in the days before the fatal stabbing on February 3.

John Crawley, IPCC commissioner for the West Midlands, said: ?Our investigation began in February but we have been unable to interview Warwickshire officers and police staff due to the on-going criminal investigation into Ms Lynch?s death.

?Now Mr Wright has been convicted we are taking steps to ensure all relevant officers and staff are interviewed.

?These interviews will be conducted under the police disciplinary procedures, our having concluded that the issues being investigated do not include any criminal offences.?

He added: ?We continue to work in close cooperation with North Warwickshire Primary Care Trust and their inquiry to ensure that any essential lessons concerning improved working between the police and care services as a result of both of these investigations are implemented.?

Wright (35), from Rugby, admitted manslaughter due to diminished responsibility at a hearing at Birmingham Crown Court on August 26, court officials said.

He was made subject to a hospital order to be detained at a secure psychiatric unit until he is no longer deemed a danger to the public.

Ms Lynch was pronounced dead on arrival at hospital following the attack, in which her mother was also injured.

Police said after the case that the order was appropriate in the circumstances.

Detective Chief Inspector Adrian Pearson said: ?There was no doubt in our minds as we dealt with Percy that he had significant issues and real experts have assessed him and they said this was the best thing for him.?
