A Chinese SWAT officer has been hailed as a hero after he carried an 80-year-old woman for some 3,300 feet to make sure she could catch her train on time.

The pensioner, who was disabled in the legs, had less than half an hour to produce a temporary ID card before she could be allowed to board her train in Haining city this week, according to People's Daily Online.

Realising the elderly passenger could miss her train, the officer who witnessed the scene immediately picked her up and carried her to make the new document, before taking her to the train.

The woman, surnamed Liu, had only realised she had forgotten to bring her ID card when she and her family reach the security control at Haining Station on Monday morning.

All train passengers must present their ID cards in order to travel in China.

Elderly Liu, who could not walk on her own, had 27 minutes to produce a temporary ID card before her train was set to leave at 8:37am.

SWAT officer, named Song Jie, saw Liu stuck by the security gate.

He told the Liu's son and her daughter-in-law, who were travelling with her, to board the train first.

Then the officer hoisted the woman up and ran out of the station.

Song carried the pensioner to a nearby photo booth to have her picture taken before dashing to the Railway Security Bureau - still with her in arms.

It took the officer 20 minutes to carry Liu back to the security gate with her document.

Song told a reporter from Haining News: 'If she had been able to walk, the process would take her around 30 minutes.

'However, she is not a local and did not know where the photo booth or security bureau was.'

Song said he carried Liu to pass the security check at 8:32am. One of his colleagues was holding the luggage for Liu.

The pair reached the platform at around 8:35am and the officer was able to carry the pensioner onto the train at the last minute.

The SWAT officer's kindness and dedication have moved many people in China, with people praising the policeman online.
