A drunken passenger caused mayhem on a Perth-bound train after he was told to stop singing football songs.

Thirty-year-old Christopher Watt responded by removing his T shirt and then began behaving “in a bizarre manner.”

Perth Sheriff Court was told that the train conductor on the Saturday evening service was so concerned that he contacted ScotRail control.

And as the conductor Barry Sewell returned to the carriage, boozed-up Watt threatened to attack him.

When the train stopped at Dunkeld at 7.30pm, the accused, who was again acting bizarrely, got off.

The police were contacted and Watt, who was minus his shirt and shoes, was arrested.

He was taken to Perth Police HQ but then unleashed a volley of abuse, calling one of the officers a “faggot and a poof.”

Watt, who represented himself, was given the chance to get legal advice after Sheriff Lindsay Foulis told him: “Custody is certainly a disposal which can’t be ruled out.”

He admitted threatening violence to Mr Sewell on the train between Kingussie and Dunkeld on May 26 last year.

He also repeatedly shouted and swore and made homophobic comments to Sgt. Frazer Robertson at Perth Police HQ.

Depute fiscal Michael Sweeney said the accused was on the 5.30pm train from Inverness and had been warned, along with another passenger, to stop singing the football songs.

The shouting and swearing, coupled with aggressive behaviour and the threat to assault the conductor followed soon afterwards.

Sheriff Foulis noted that the accused has a number of convictions, some of which were directly analogous.

He was also subject to a community payback order, which had been the subject of a breach report.

Watt, of Eastermains, Kirkintilloch, will be sentenced on May 15.

The Sheriff said: “I am duty bound to give you the opportunity to obtain legal advice.

“I strongly suggest you do.”
