A man originally from Limerick has been given an indeterminate sentence for the manslaughter of a police officer in Derry in February last year.
PSNI Constable Philippa Reynolds was killed when a stolen vehicle crashed into her police car in the Waterside area of Derry.
The court was told that 26-year-old Shane Frane, who was living in a homeless shelter at the time, had spent the day drinking and taking drugs before driving the stolen vehicle at high speeds.
Frane, who was described as a dangerous offender, who had 77 convictions in the Republic and 12 in the North, was given an indeterminate sentence for the manslaughter of Constable Reynolds and other offences.
The judge ordered that he serve six years in prison before parole commissioners decide if he can be released.
The court was told that Frane presented a high likelihood of reoffending and was a significant risk of serious harm.
Another man, 24-year-old Conor Clarence, who was a passenger in the stolen car, will serve 21 months in prison.
