Police are being investigated over the handling of a 999 call after a fisheries boss was fatally shot.

The Independent Police Complaints Commission (IPCC) is looking into the moments after Steve Langley was shot in Tonge by a former colleague who harboured a long-standing grudge against his former boss.

Simon Olsen was jailed for life yesterday, and told he would have to serve a minimum of 25 years before being considered for parole.

The court heard he blasted the former Medway firefighter in the stomach at a tackle store in Lower Road, Tonge, near Teynham, after becoming convinced he was laughing at him behind his back.

Homeless Olsen, 54, held a long-standing grudge against his former boss Mr Langley, who ran Bax Farm Fisheries lake in Tonge, close to the murder scene.

The matter was referred to the IPCC in December last year, days after 57-year-old Mr Langley was shot on November 29.

It followed a complaint from the South East Coast Ambulance Service about how the emergency call had been handled.

A statement issued today revealed: "The IPCC is looking at the actions and decisions made by Kent Police in their handling and response to the call and the three-way radio communication between Kent police, the caller and the ambulance service.

"The investigation is also examining the treatment and care of Mr Langley after officers attended the scene of the shooting."

Investigators have listened to audio recordings of the emergency call and taken statements from both an ambulance worker and the police call handler.

Statements gathered as part of the murder prosecution have also been considered.

IPCC Commissioner Mary Cunneen said: "It is important that we have a full understanding of the communication between the ambulance and police services in response to an emergency, and of the care provided to Mr Langley once he had been shot.

"I decided there should be an independent investigation into the police actions in respect of these aspects of Mr Langley's death.

"Our thoughts remain with Mr Langley's family and friends at this difficult time. "

There is no evidence to suggest any police staff member committed a criminal offence or breached their standards of professional behaviour.

The investigation comes as the IPCC also probes police call handlers after a Anne-Marie Birch was strangled and beaten to death in Broadstairs last year.

A control room leader, supervisor and two call handlers have been served with notices by the Independent Police Complaints Commission (IPCC).

The investigation is looking at potential gross misconduct, after it was said they dealt with phone calls from Mrs Birch just days before her death.
