An investigation has been launched after a patient jumped 20ft from a window at Blackpool Victoria Hospital.
The Health and Safety Executive (HSE) confirmed it is now probing the incident, which happened at around 2.35pm on New Year’s Day.
The man, who was in a private room, survived the fall and is receiving treatment for his injuries. They are not thought to be life-threatening.
One eye-witness said it looked as though the man had jumped from a third-floor window.
The circumstances surrounding the fall remain unclear with hospital chiefs saying they could not comment in detail about the incident or the ongoing investigation, which is expected to last several weeks.
Staff will be interviewed as part of an internal investigation.
The first meeting in relation to the matter was scheduled to take place this afternoon.
A spokesman for Blackpool Teaching Hospitals NHS Foundation Trust said: “We can confirm that a patient fell from a window at the hospital and is receiving treatment for the injuries they sustained.
“An investigation into the incident is is to take place and it would be wrong to comment any further at this stage.”
No members of staff have been suspended as a result of the incident.
A HSE spokesman confirmed the regulator would be making its own enquiries into events at the hospital.
He added: “It has been reported to us and the HSE is investigating. We will now try to ascertain what happened and why.”
HSE will then publish its findings in a report, which may take months to complete.
Police confirmed they were called out to the incident but will not be pursuing the matter.
A spokesman for Lancashire Police said: “We had a call to say that a man had either fallen or jumped about 20ft out of a window.
“He was breathing and conscious at the time. This is not a police matter and we are not investigating.”
