BROOKLYN — A mother was sucker punched while crossing a Midwood street with her 7-year-old daughter in broad daylight, police said.

The 33-year-old mother was near the intersection of 12th Street and Elm Avenue in Midwood about 2:45 p.m. Saturday when a man approached her from behind, swung at the back of her head and knocked her to the ground, police said.

Nothing was reported stolen. The woman sustained minor injuries to her hands and knees, police said.

The attack appears to follow the pattern of the alleged “knockout game" assaults that have taken place over the past couple of months in Midwood and Crown Heights.

In the knockout game, a random victim is punched in the head and knocked to the ground. Nothing is stolen during the assault.

Police did not immediately say whether they were investigating Saturday's assault as part of the knockout pattern.

Police described the suspect as a man with short braids, about 5-foot-8 and weighing 180 pounds. He wore a black wool cap, green jacket, and dark jeans, officials said.

Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS (8477).
