IOPC is investigating potential errors in force’s dealings with Jake Davison, who killed five people in August
The investigation into the Plymouth mass shooting has placed one police staff worker under investigation for gross misconduct, meaning they could be sacked if allegations are upheld.
Jake Davison, 22, shot dead his mother, a three-year-old girl and three other people on 12 August. He used a gun he had held a licence for since 2017, which had been taken away after he got into a fight in September 2020, only to be returned by police weeks before the killings.
