A recent attack on a train driver left the young professional in need of emergency dentistry and police are now appealing for help to catch the perpetrators.
The unnamed 22-year-old had been driving a South West Trains service from Alton to Woking when the incident occurred on January 12th 2011.
A conductor discovered two men were travelling without valid tickets and they pulled the emergency stop cord when they were confronted.
The driver went to assist his colleague, but was punched in the face by one of the passengers and needed emergency dentistry for loosened teeth.
British Transport Police has released CCTV footage and is offering a reward for information that will help catch the men involved.
Investigating officer detective constable Tony Bronger said: "This was a nasty attack on a man who was simply doing his job."
Should the driver experience problems with his loose teeth, he could have cosmetic dentistry to have them replaced with dental implants. These are often praised by dentists for their realistic look and sturdiness.
