Vicious attack on tweens

Rolling rage

A crew of thugs gershed the bicycles from two 12-year-old boys on Nov. 19 during a violent exchange in front of the Brooklyn Museum.

The victims were pedaling past the corner of Eastern Parkway and Washington Avenue at 3 pm when the four suspects jumped them, ordering them to give up their wheels.

“Give me the f—king bike!” one of the thieves screamed as he pushed his victim onto the sidewalk, causing the pre-teen to hit his head on the concrete.

Backpack swipe

A bubbly thief made off with a 22-year-old woman’s backpack on Nov. 21 during a visit to Bubbleworks on Washington Avenue.

The victim told police she was inside the Laundromat between Prospect Place and St. Marks Avenue at 7:20 am when she turned away from her bag for just a moment. When she turned back, her backpack was gone.

Clean getaway

A thief made off with a woman’s purse on Nov. 24 as she did her laundry inside a Dean Street building.

The victim left her purse on a chair inside the building between Sixth and Carlton avenues at noon. The thief palmed the bag when she turned away from her purse to fold her clothes.

Houdini gershing

A clever thief managed to free a bike secured to a fence on Sterling Place on Nov. 21 — without tampering with the lock or the chain!

The 50-year-old bicyclist told cops that she had locked up the bike between Washington and Underhill avenues at 6 pm before attending a nearby party. When she returned an hour and a half later, the lock and chain were still on the fence — but the bike had been gershed.

Prospect predator

Two Prospect Place homes were raided on Nov. 27. Here’s how it went down:

• A thief broke into a home between Vanderbilt and Underhill avenues between 4 pm and 4 am the next day, taking an iPad, digital camera, Blackberry and his victim’s birth certificate. The victim told police that the thief forced open a bedroom window in order to get inside.

• An antique sword was among the items stolen from an apartment between Grand and Classon avenues.

The victim left his apartment to go food shopping at just after noon when the thief pushed in an air conditioner.

When the victim returned 15 minutes later, the sword and a jar of change were missing.
