A 32-year-old man from Cardiff will appear in court accused of defecating in a lift at Ystrad Mynach railway station.
British Transport Police last week issued an appeal for information about the incident.
Officers said a disabled woman who used the lift after the man was very upset.
Christopher Morgan, of North View, Cardiff, has been charged with soiling the railway contrary to Byelaw 6 of the Railway Byelaws and one count of criminal damage.
Well done British Transport Police – a good result !
All that clown had to do, was find a bush, and do his business away from the station, plenty of them in Ystrad Mynach.
