Kam Brock is a 32-year-old woman from Long Island, New York, who was driving her 2003 BMW through Harlem in upper Manhattan last September 12 when police pulled her over, accusing her, wrongly, of being under the influence of marijuana. They found no drugs in her car, but the police just didn’t want to let the woman off the hook.

What followed was a ordeal that lasted more than a week and could have been taken out of a novel by Kafka — or a Hollywood horror movie.

The police confiscated her beloved BMW and when she showed up to retrieve it the next morning, they handcuffed her because, she says, she was “emotional.”

Next thing she knew, she was confined to a mental hospital.

The allegations come from a lawsuit Brock has filed against the city, and that was uncovered Monday by the New York Daily News. But according to the News report, “a ‘master treatment plan’ from Harlem Hospital backs up the Astoria Bank worker’s story.”

When she tried to tell the doctors she was “a good person, a positive person” whose reputation was upstanding enough that Barack Obama himself follows her on Twitter, they locked her in a mental ward and filled her full of drugs for eight days.

In fact, as a condition of her release, doctors required that she “state that Obama is not following her on Twitter.”

There’s only one problem. Kam Brock, “emotional” though she may have been, was telling the truth. Barack Obama — or at least whoever is assigned to operate the president’s personal Twitter account — does indeed follow her on Twitter, along with more than 640,000 other people.

The police and doctors could have easily checked and verified that fact simply by looking through Brock’s own Twitter account.

Instead, they declared her “delusional” and “bi-polar,” and confined her to the psychological unit at Harlem Hospital.

“Next thing you know, the police held onto me, the doctor stuck me with a needle and I was knocked out… I woke up to them taking off my underwear and then went out again. I woke up the next day in a hospital robe.”

Medical records attached to Brock’s lawsuit show that for more than a week, doctors shot her up with sedatives and forced her to consume the powerful psychoactive drugs lorazepam — also known by the brand name Ativan — and lithium.

But even when the doctors finally let her out of the hospital, Kam Brock still had even more craziness thrown her way, this time in the form of a medical bill for her “treatment” in the hospital — a bill for a whopping $13,637.10.

Kam Brock is suing to get that money back, as well for unspecified damages. Watch a New York Daily News video report on her bizarre ordeal, above.
