A prosecutor says Christopher Loeb, the man whose arrest years ago led to the downfall of Suffolk County's former top cop, was high on multiple drugs when he drove more than 100 mph on the Long Island Expressway.

Loeb used a walker as he stood before a judge Thursday in Riverhead. The Mount Sinai man claims his leg is infected from several police K-9 bites. Loeb says Suffolk police intentionally sicced their K-9 on him following a high-speed chase last month.

Loeb was arraigned on a 15-count indictment that includes assault and reckless endangerment charges. He's accused of driving onto several front lawns, ramming two separate Suffolk police cars and then leading police on a 22-mile, high-speed chase from Ridge to Islandia. The prosecutor said in court Thursday that Loeb drove more than 100 mph and was high on Xanax, cocaine and bath salts.

The ordeal began on Lakeside Trail in Ridge, where a woman who was outside with her dog had to jump out of the way as the car came up on her front lawn.

Loeb's attorney told the judge that his client fled the police because he has a "psychological issue in regards to his prior police contact." As News 12 has reported, former Suffolk Police Chief James Burke was convicted in federal court of beating up Loeb in 2012 and trying to cover it up.

Loeb's family was in court Thursday but wouldn't speak with News 12.

Loeb received a $1.5 million settlement from Suffolk County last year as a result of the Burke incident. Loeb's attorney said Thursday that his client has the money for bail but won't post it so he can get immediate drug treatment.

The judge told Loeb "this stuff can't happen anymore, people could have gotten hurt." He then set Loeb's bail at $100,000.

The Suffolk Police Department is not commenting on Loeb's claim that police released the K-9 when he was already willing to surrender and that it was unnecessary.
