Emergency crews move a man into a life-flight helicopter on Sixth Street between Kentucky and Tennessee streets on Friday, Sept. 16, 2011.

A 31-year-old Lawrence man was transported by helicopter after falling and hitting his head early Friday morning.

A Lawrence police officer on the scene said the man had been walking, and had fallen and hit his head on the pavement. He was thought to be impaired by a substance, and it did not appear he was pushed.

Sixth Street was shut down between Tennessee and Kentucky streets to make a landing area for the helicopter. The helicopter took off with the man at around 2:35 a.m., and was expected to land at Stormont-Vail Healthcare in Topeka.

No information on the extent of his injures was immediately available.
