Superintendent David Taylor has tonight been reinstated to his position in An Garda Síochána with immediate effect.

The former Garda Press Officer was the Superintendent in charge of the Traffic unit at Dublin Castle before he was suspended in 2015 as part of an investigation into alleged media leaks.

However, the DPP today directed he was not to be prosecuted

Supt Taylor said in a statement today he had been vindicated, that it had been an incredibly stressful and difficult time for himself and his family and that he had waited a long time for this decision to be made

He was contacted by a senior officer tonight and informed that his suspension was lifted and he was to report back to work immediately.

The superintendent had been suspended for 22 months during which time he had been arrested and questioned for 21 hours at Balbriggan Garda Station.

He also had his pay reduced at one stage by 25% but all monies are due to be repaid to him.

The investigation began into leaks of information relating to the Roma children controversy.

The investigation was led by Chief Superintendent Frank Clerkin assisted by Detective Superintendent James McGowan, Garda Commissioner Nóirín O’Sullivan’s husband.

Supt Taylor's solicitors were informed this afternoon that the DPP has directed there should be no prosecution in relation to the investigation.

Supt Taylor also made a protected disclosure to Minister for Justice Frances Fitzgerald, in which he said he was directed by senior garda management to spread malicious rumours about Sergeant Maurice McCabe.

He said that Commissioner O'Sullivan was kept fully briefed on the smear campaign at all times.

The protected disclosure was the basis for the O'Neill Inquiry which recommended that the allegations be tested by a Commission of Investigation.
