A nurse has been giving evidence at the inquest into the death of 34-year-old plumber David Hagen.
Lyn Farrer was on duty on Mr Hagan's ward at the time. She said she had tried to stop Mr Hagan leaving by holding his arm but he had brushed her aside.
Ms Farrer said she then tried to contact the hospital security but was told there was no one on duty.
Another nurse tried to follow Mr Hagen but he left the hospital.
The police and the hospital's Crisis Team were informed and a description of him issued.
He died just a few hours later at Engine Lonning in Carlisle.
Ms Farrer told the inquest that there was no formal plan on the ward to deal with high risk patients who might abscond but that staff had now been retrained.
The inquest continues.
