- Charlie Vaughan, 25, spent three months transmitting the nuisance broadcasts
- Messages he sent included 'enjoy the bomb' and 'I am going to cut your throat'
- Broadcasts forced Southampton port authorities to talk to vessels via mobiles
- He was charged with sending malicious electronic communications
- Judge handed him 18-month prison sentence suspended for two years
A radio hijacker who stopped vessels receiving directions as they approached port by transmitting music, racist abuse and threats to make a bomb on the frequency used by maritime authorities has avoided jail.
Charlie Vaughan, 25, spent three months disrupting communications for vessels sailing into and out of Southampton port.
He sent messages including 'enjoy the bomb', 'I am going to blow up your ship' and 'I am going to cut your throat', as well as racial slurs against Polish, Chinese and black people.
Port authorities were forced to give vessels directions via mobile phones and, at one point, had to send a tug boat to pull a 1,000-foot cargo ship, one of the largest in the world, into port.
Vaughan, who is unemployed and supported by his partner, was only stopped when he was traced by Ofcom engineers.
He pleaded guilty to a charge of sending malicious electronic communications at Southampton Crown Court and was sentenced to 18 months in prison, suspended for two years. This included a six-month sentence for assaulting two emergency workers on April 29 last year.
Prosecution barrister, John Upton told the court Vaughan used special equipment to send nuisance transmissions on the same radio frequency as Vessel Traffic Services - the maritime equivalent of air traffic control.
The court heard how his actions could have easily caused a ships to sink, collide or led to people getting killed.
He sent more than 400 messages over the maritime channels between April 1 and June 27 this year.
He was only traced after Ofcom engineers got involved, and spent more than 450 hours trying to locate the source of the signals.
Sentencing him Judge Gary Burrell QC said: 'This is a very, very serious case. It endangered the safe navigating of ships on the Solent.'
He was also ordered to pay £1,335 court costs.
When he was arrested, police found him lying on his bed surrounded by three handheld radios. He had been given two by his partner as a birthday present.
He also had a selection of radio user guides and manuals.
Defence barrister Mark Florida-James said his client had mental health issues and suffers from ADHD and Asperger's syndrome.
A statement from Vaughan read on his behalf said: “Sorry. I really am sorry for the upset I have caused.”
