A teenager who punched a woman in the face has been jailed for three months.
Michael Connors, of Strabane Old Road, pleaded guilty to one charge of common assault.
The charge relates to an incident in the Foyle Street area of the city on November 15, last year.
Derry Magistrates Court heard the injured party was along with friends in a park in Foyle Street. Connors got into an argument with her friends and the injured party attempted to get him away.
The court heard the 19-year-old then punched the woman in the face. She received treatment in Altnagelvin Hospital.
During police interview Connors denied the assault.
Defence counsel Stephen Chapman told the court his client has 20 previous convictions, but there is nothing similar on his record.
He added that Connors is a sentenced prisoner and is not due for release until May next year.
Jailing the 19-year-old for three months, District Judge Peter King said it was a ‘nasty unprovoked assault’.
