Shana Grice was killed by her stalker ex-boyfriend in her bedroom in 2016

Two officers face disciplinary action after a teenager who reported her stalker ex-boyfriend was fined for wasting police time months before she was killed.

Shana Grice endured months of stalking and harassment from her obsessed former lover, Michael Lane.

The 19-year-old reported her ex-partner to Sussex Police five times in six months, but was fined £90 for wasting police time and handed a with a fixed penalty notice.

Just months later Lane attacked his former girlfriend and slit her throat with a knife before setting fire to her bedroom to try to burn her body in Portslade, near Brighton, East Sussex, in 2016.

Sentencing judge Mr Justice Nicholas Green criticised Sussex Police for siding with the stalker when he jailed Lane for life with a minimum term of 25 years in March 2017.

A total of 14 officers were investigated by the police watchdog in the wake of Miss Grice's murder.

Two police officers, one of whom has retired, will face gross misconduct proceedings in front of an independent chairman at public hearings on May 7 and 10, Sussex Police confirmed this evening.

Another police officer will face internal misconduct proceedings, which are carried out in private.

No further action will be taken over five other officers investigated by the Independent of Police Conduct (IOPC), while six other force employees – three officers and three staff – have already been handed 'management advice and further training'.

The IOPC is understood to be recommending 18 new training measures for the force when it announces the findings of its investigation on Wednesday, according to Channel 4 News.

Lane's trial prompted widespread calls for action to ensure victims are taken seriously by police.

He pursued Miss Grice by fitting a tracker to her car, stole a house key to sneak into her room while she slept and loitered outside her home. It later emerged 13 other women had reported him to police for stalking.

Singer Lily Allen, who was stalked for seven years, branded the case an example of police 'continuing to ignore' warning signs.

At Lane's sentencing, Mr Justice Nicholas Green said officers 'jumped to conclusions' and 'stereotyped' Miss Grice.

Her Majesty's Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) is due to publish its findings on how stalking and harassment cases are handled by police on Wednesday.

The inquiry was ordered in the wake of Miss Grice's murder.

Assistant Chief Constable Nick May said: 'We deeply regret the tragic death of Shana Grice in 2016 and are committed to constantly improving our understanding of stalking and our response to it.

'When we looked at the circumstances leading to Shana's murder, we felt we may not have done the very best we could and made a referral to the IOPC.

'Our then-deputy chief constable personally visited Shana's family to apologise on behalf of Sussex Police.

'Since then we have undertaken all their recommendations, thoroughly reviewed all aspects of how we deal with cases of stalking and harassment and have significantly improved our service to victims.

'We are recording the second highest number of reports anywhere in the UK after the Met, and are now advising and supporting more victims than ever. With better awareness and enhanced training our approach is more robust in keeping people safe and feeling safe.

'We encourage victims to come forward with the knowledge that our officers and staff are better trained and that they will take all reports seriously.

'We are absolutely aware of the consequences if our response is not the correct one, so we want to ensure that victims have confidence in how both police and the CPS will support them.'

The news comes on the same day the IOPC announced a police call handler from the same force was given 'management advice' after failing to record a woman's reports of escalating violence by her ex-husband who shot her dead eight days later.

Michelle Savage spoke to Sussex Police three times before she was murdered alongside her 53-year-old mother Heather Whitbread in an execution-style killing at almost point-blank range in St Leonards, East Sussex, on March 16 last year.

She had told officers former soldier Craig Savage was dangerous and she feared for her life.
