Leon Gibbs, 38, a Preston Bus driver, from Ribbleton, witnessed the dramatic fall as he pulled into the bus station.

He said: "The girl was holding onto him with two hands - I thought she was going to go over with him.

"While she had hold of him it looked like she could not pull him up - she was a lot smaller."

A witness who was inside the bus station when the incident took place, said: "I saw a pair of legs dangling down.

"I think his babe had hold of him then I saw him drop - he was knocked out.

"I heard the crack."

A spokesman for Lancashire Police, said: "A woman we believe to be his partner tried to grab him as he fell.

"He is going to be kept in hospital over night but he is expected to be released tomorrow."

Police re-opened the bus station at approximately 5.15pm on Tuesday.
