A trespasser has made their way onto train tracks this morning and it is causing delays for two rail companies.
National Rail have been advised of a trespasser on the tracks between Streatham and Tooting.
As a result, the lines between Tooting and West Sutton via Wimbledon are blocked and some Southern and Thameslink trains will be unable to run.
Emergency services are currently on site and "dealing with the situation."
The issue is expected to last until at least 10.30am, with National Rail expecting residual delays.
