A SECURITY guard at the oil fuel depot near Faslane has been filmed apparently making chilling threats and hurling foul-mouthed abuse at a teenage cyclist.

Audio and video footage shared with the Advertiser appears to show the security guard at the depot, located to the north of Faslane itself, telling 18-year-old Alex Sidney: “When I’m out in my car you’re going to come off that f***ing bike”.

Alex told the Advertiser he had been cycling in the area last Friday, (May 7) and had stopped to take a drink of water on the public road which runs alongside the depot.

In Alex’s video recording, a security guard inside the oil depot’s boundary fence can be seen approaching him and apparently being verbally abusive.

In the audio recording the same voice can be heard telling Alex to “f**k off”, before saying “Why you being a c**k? Have you got nothing better to do with your f***ing time?”

Throughout the incident, Alex – who is a resident of the Faslane peace camp, and who featured in the Advertiser recently after his rides around Helensburgh on his Tall Bike caught the eyes of local residents – remains silent.

The guard continues: “You’re just an a******e eh? A f***ing waster in life.

“If I had my way, you wouldn’t be sitting up on that f***ing bike. When I’m out in my car, you’re going to come off that f***ing bike.”

In the separate video recording, the guard is heard telling Alex to “give me a pose” before calling him a “f***ing c*** s***er”.

The oil depot is run by the Oil and Pipelines Agency, a public corporation of the Ministry of Defence.

Alex said: “I was on a bike ride and pulled into a lay-by for a water break, next to one of the closed gates to the oil fuel depot. The guard came out and started shouting at me.

“I was always on public land but he seemed to think it was MoD property, despite having asked police later, who confirmed that it was public.

“I was never blocking any entrances or causing any disruption to work or traffic so I don’t see what the issue was.

“I had just stopped for a few minutes to catch my breath, but evidently this guard was already in a bad place and wanted to take out his frustration on somebody.

“I’m not bothered by the remarks, but my main worry is that they are paid to be professional, and if they are not doing that, and instead are verbally abusing people, then that might not be the right line of work for them.”

An MoD spokesperson said: “The MoD Guard Service does not condone offensive behaviour.

“We are aware of this incident and the matter is currently being investigated.

“It would be inappropriate to comment further at this time.”
