HALES CORNERS, Wis. — A suburban Milwaukee fireworks show was cut short after a fireworks technician was injured.

The display at Hales Corners Park started at 9:28 p.m. Thursday but stopped after four bursts of fireworks were fired from a wooded area. Then spectators saw flashing lights on emergency vehicles and sirens.

In a news release Friday, police said the firework exploded on the ground inside the launch tube.

Police say the man suffered a fractured left leg and other injuries to the left side of his body and face.

The rest of the show was canceled. Police destroyed the remaining fireworks.
