Police are looking for a man they say walked past a 79-year-old standing in the mezzanine area of a Queens subway station and punched him in the head for no reason at all, authorities say.
The victim was attacked in the middle of the afternoon -- around 2:30 p.m. -- Saturday at the Junction Boulevard station, which serves the No. 7 line.
The impact of the blow sent the 79-year-old flying backward into a wall and then to the ground, suffering a laceration to the back of his head in the process.
The victim was taken to a hospital for treatment, while the suspect fled the scene.
