A train company has threatened to sue a member of the public after he set up a parody Facebook account to mock the firm's frequently late-running trains.

Arriva Trains Wales warned Steven Fletcher he could face legal action over the account called 'Arriva Trains Fails - Wales'.

The page, which was set up in 2014, pointed out late-running trains and other mistakes, and has amassed more than 4,000 likes.

Fletcher is a member of Arriva's Passenger Panel, a "consumer forum that represents the demographic of customers that use our network".

The panel's profile page describes Fletcher as a "regular commuter on the Cardiff Valley network" who "urrently runs a website with more than 3500 active train-using members, from a variety of different backgrounds, showing his keen interest in helping improve train services.

"He has been proactive and enthusiastic when providing us with information to improve our service".

However, Arriva bosses were left red-faced after a simple Google search for their company returned Fletcher's logo rather than their own, and has threatened him with legal action if he doesn't remove it.

Mr Fletcher, of Cardiff, posted from the parody account page: "So, the #Logogate latest:
