The woman, believed to be in her 70’s had suffered a seizure and was later seen boarding a train at Manchester Piccadilly Station.
Police are searching for a pensioner who went missing from hospital and boarded a train.
The woman was taken to Manchester Royal Infirmary after suffering a seizure in Manchester city centre on Saturday morning.
While waiting for treatment the woman, who is believed to be in her 70’s, left the hospital, the Manchester Evening News reports.
Police enquiries have since established that the woman took a bus to Piccadilly where she is then suspected of boarding the 1.31pm train from Manchester Piccadilly to Carmarthen in Wales.
Officers say they are becoming increasingly concerned for the safety of this woman and are asking for the public’s help to identify both her and her whereabouts.
Inspector Andrew Torkington, of Greater Manchester Police’s City of Manchester division, said: “We are aware that this woman left hospital without treatment and want to locate her as quickly as possible to ensure that she is safe and well.
“We believe she could have been visiting friends or family in the Manchester area and have released a CCTV image in the hope that someone will be able to help us identify this woman and her whereabouts.
“We would like to make it clear that she is not in any trouble, we just want to identify her to ensure that she is safe.”
