An inmate at the Ulster County Jail faces a felony charge for allegedly keeping a Xanax stash, the Ulster County Sheriff's Office said Friday.

Edgardo D. Jagr, a 44-year-old man from Marlborough, has been at the county jail since Sunday, after cops arrested him for allegedly breaking into a motel in Saugerties and assaulting his ex-girlfriend.

Jagr was jailed on $25,000 cash bail and charged with felony burglary and misdemeanors, including a charge for obstructing breathing or blood circulation. The latter charge is usually levied against suspects accused of strangulation. The charge was created in 2010 by state lawmakers.

After receiving a tip on Tuesday about prescription drugs circulating in the jail, cops began an investigation.

Jagr was additionally charged with first-degree felony promoting prison contraband and misdemeanor drug possession.

It wasn't immediately clear how the new charges would impact bail or potential penalties. Jagr, who did not have an attorney listed in records, was not yet arraigned on the new charges as of Friday afternoon.
