Passengers on Thameslink trains from Sutton to Luton are being warned that services are not stopping at some stations due to an emergency.

Tooting and Haydons Road are closed to passengers wanting to alight or get on as emergency services attend an ongoing situation.

Thameslink posted a tweet informing customers that services on this line are also experiencing a half hour delay for the time being.

Train tickets for this service will be accepted on buses and the London Underground via "any reasonable route" as an alternative.
