"Black Madam" Padge Victoria Windslowe was arrested by Philadelphia police on Wednesday for allegedly administering illegal “butt-boosting” injections, which may have caused the death of a 20-year-old British woman last year, reported ABC News.

Windslowe, 42, a transgender woman, was arrested on Wednesday at a home while hosting a "pumping party," according to the American news station. When she was taken into custody, she had needles, Super Glue, cotton balls, paper towels and a pink bag with a 20-ouce water bottle containing what police believe was the substance she was about to inject into other party-goers.

Windslowe's arrest came after one of her clients, an exotic dancer, 23, suffered lung problems following an injection last month, reported BBC News.

According to USA Today, the problems were serious enough to have the woman spitting up blood after getting the injection. She had paid $1,000 for what she believed was a silicone injection, reported ABC News.

Windslowe was charged with aggravated assault, simple assault, recklessly endangering another person, deceptive practice and related offenses. Her bail is set for $10 million, according to the Associated Press and ABC News.

Windslowe is also a "person of interest" in the death of a 20-year-old British woman named Claudia Aderotimi, who received injections at a hotel near Philadelphia International Airport last year, reported the Associated Press. According to Philadelphia police Lt. John Walker, she will likely be charged with murder if the medical examiner rules it was Windslowe's injection that caused the woman's death, which came after she complained of chest pain and difficulty breathing following the procedure.

"We knew she was the injector back in the 2011 (Aderotimi) case," Walker said to the AP, adding that the investigation had been put on hold while police awaited a ruling on cause of death.
