A heartless thief swiped a pricey wheelchair from a Brooklyn woman with multiple sclerosis, authorities said.

The 36-year-old woman stopped her Drive Titan motorized wheelchair in front of Weichert Realtors in Gravesend at around 3:30 p.m. Saturday.

The woman — who is able to walk short distances — entered the building, leaving her Titan unattended.

The wheelchair, which can retail for over $3,000, caught the attention of the opportunistic creep, who rolled away with her ride, police said.

The suspect is a man last seen wearing a hoodie, jeans, a wool knit cap and glasses.

Anyone with information is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS.
