Noel Gallagher is recording a new album with Oasis

Officers from the British Transport Police interviewed the star at a music studio near Golant, Cornwall.

Inspector Kevin Marshall said Gallagher "fully admitted" the offence of trespassing and a decision will now be taken whether to prosecute him.

The maximum penalty for the offence is a �1,000 fine.

A photograph of Gallagher walking on a railway line in Cornwall appeared in The Sun on Tuesday, near to the Sawmills Studios where Oasis are recording their next album.

Following publication of the picture, British Transport Police made it known they wished to speak to him as they feared he was setting a bad example.

Options

Insp Marshall told BBC News Online: "Following a photograph which appeared in a national newspaper on 2 February 2004, around 11am this morning officers from the British Transport Police interviewed Mr Noel Gallagher in relation to him trespassing on the railway line.

"Mr Gallagher fully admitted the offence at Golant, Fowey, in Cornwall, and he was reported for a decision to be made as to whether he could be prosecuted or not."

He said there were three options open to police in deciding how to deal with the offence: summoning him to appear in court; a caution; or being sent a warning letter.

Insp Marshall added that trespassing on the railway line was a potentially dangerous activity.

The Rail Safety And Standards Board recently criticised pop band Liberty X for filming a video on a railway line, saying it could encourage children to play near them.

The group defended themselves by saying there was never any danger because it was all recorded on a disused line.

Meanwhile, rock band The Darkness have retaliated in their war of words with Oasis after Noel recently said the band "doesn't do anything for me".
