London Midland has vowed to give police CCTV images of a 'disgusting' passenger suspected of defecating inside a train carriage as it travelled through the Birmingham area. The passenger who made the awful discovery said the smell was so bad that it forced the operator to cancel the service from Lichfield Trent Valley to Longbridge. It plunged commuters into hours of misery as the act of vandalism on the Cross City line caused severe delays. A passenger made the awful discovery on a train travelling between Lichfield Trent Valley and Longbridge . Passenger Christopher Talbot told the Birmingham Mail he was heading to work on the 7:50am service on Thursday when he found  excrement in a newspaper on the floor. He said: ‘As I sat down I saw a newspaper on the floor. I leaned over and noticed there was something inside it. ‘It looked like poo basically. The smell was going through the carriage. These trains have toilets on.’ The 52-year-old, who works as a cleaner at a school, said there was only one other passenger in the carriage, and he reported the incident to platform staff when he disembarked at Butlers Lane in Four Oaks. London Midland said that CCTV images of the culprit would be passed onto police for investigation . The service terminated at Birmingham New Street so that the carriage that was used as a toilet could be cleaned. Normal service resumed at about 9:30am. A Network Rail spokeswoman confirmed to MailOnline Travel that excrement was discovered inside a carriage. A spokesman for London Midland said the 'act of vandalism' was 'disgusting'. The service terminated at Birmingham New Street so that the carriage could be cleaned . He added: ‘It was necessary for the train to be cleaned before we could continue to let passengers onto the service. ‘I would like to apologise to our genuine passengers who experienced the disruption.’ London Midland confirmed that CCTV images of the culprit, who fled the train, would be passed onto police for investigation. A British Transport Police spokeswoman told MailOnline Travel that it has no record of a formal complaint being filed. A similar incident occurred last month when a British Airways flight was forced to return to London after a foul odour emanated from an overflowing toilet. Passenger Abhishek Sachdev, a councillor who represents Potters Bar Parkfield, said the seven-hour flight to Dubai was aborted ‘because of a smelly poo in the toilet'.
