A soldier seen fighting in the street told police he would be back to cause havoc in the town centre.
Anthony Martlew, 23, who is based at Weeton Army Barracks, Weeton, pleaded guilty to being drunk and disorderly.
He was fined £100 with £85 costs and ordered to pay a £150 court charge plus £20 victims’ surcharge by Blackpool magistrates.
Martine Connah, prosecuting, said a police officer patrolling Queen Street, Blackpool, on December 1 at 4.40am, saw Martlew throwing punches at two men.
The officer tried to stop him, but Martlew kept swearing telling the officer to get off him. Two door security officers helped the officer restrain Martlew, who said he would come back and cause havoc.
