A Buckfast-wielding yob dropped his trousers and bared his buttocks at a Remembrance Day memorial monument.
Brent Conway forced horrified diners to leave nearby cafes because they were so shocked by his behaviour.
A court was told security staff from St John’s shopping centre had to tackle Conway after he ignored numerous pleas to leave the monument.
Conway was with others drinking on the King Edward VII monument in Perth.
Depute fiscal Matthew Kerr told Perth Sheriff Court yesterday he was asked to leave by security staff.
He said: “They returned a short time later and could both see the accused exposing his bare buttocks to members of the public.
“He was continuing to shout and swear. Several members of the public had been sitting outside enjoying the sun and they started to leave due to his behaviour.
“He was asked to leave again and appeared to walk off. At 3.15pm security staff were aware he had returned. He was holding a Buckfast bottle.
“They told him to leave a third time. He approached one of the guards with his arms outstretched, holding the bottle in an aggressive manner.
“Five minutes later the police attended and saw the accused being restrained on the ground by one of the security staff from the St John’s Shopping Centre.
“He was continuing to shout, swear and act in an aggressive manner, so he was taken to custody.”
Conway, 23 from Perth, admitted causing fear or alarm to the public on 30 May last year.
Sentence was deferred until July for good behaviour.
