A man who was disorderly in the local hospital has been jailed for three months.
Daniel Armstrong, whose address was given as no fixed abide, pleaded guilty to disorderly behaviour and assaulting police.
The charges relate to an incident on February 22, last year.
Derry Magistrates Court heard that police spoke to the 21-year-old on the Strand Road and arrested him for other matters.
He had a laceration to his thumb and finger and police took him to hospital for treatment.
The court was told the waiting room was ‘busy’ and Armstrong started using offensive language.
He told the officers to ‘f*** off’ and called them ‘black b*******’.
The 21-year-old also told one of the officers ‘I will get you with a flying head butt’ before violently lunging towards him.
Defence solicitor Seamus Quigley told the court Armstrong was on a ‘cocktail of drink and drugs’ at the time.
He added his client wished to apologise.
