A woman has been arrested after practising yoga poses in the middle of a Washington D.C. subway track.

The suspect, who is believed to be Holly Bentley from Virgina, has been charged with criminal trespassing.

The following image was found on Bentley's Instagram account, underneath which she wrote: 'Apparently getting into the tracks on the DC Metro is a big no-no. I didn't know.'

In December of last year, Bentley is believed to have climbed onto the tracks with a photographer friend at West Falls Church station in Washington D.C.

At one point the suspect appears to stumble, coming dangerously close to the high voltage rail.

Bentley's Instagram account has over 10,000 followers and frequently posts pictures of herself in yoga poses.
