Timothy Young had just turned into a petrol station in the small US town of Lorsburg, New Mexico, and was about to fill up his pickup truck when several police cars pulled up behind him.

The officers from the Hidalgo County Sheriff’s Office accused him of failing to use his indicator, and asked him whether he was using or carrying drugs.

According to a complaint filed in the federal court in New Mexico, what happened next in the October 2012 incident was nothing short of a six-hour nightmare.

Young, 31, was forced to strip from the waist down in a public carpark and then submit his body to an X-ray and anal penetration at a nearby hospital, all under the supervision of peace officers searching for contraband.

The invasive search that Young alleges he was subjected to is not an isolated incident, his lawyers say, and is part of a larger pattern of cops, eager to make drug busts, crossing the line in order to try to uncover drugs and money at all costs.

“They’re really pushing the envelope on these types of searches of people,” said Joe Kennedy, an Albuquerque lawyer who is representing Young.

Complaints about police conducting public full-body cavity and strip searches, sometimes without warrants, have popped up in Texas, Wisconsin and Kansas in recent months, alarming civil rights attorneys and advocates.

In Young’s case, the officers searched his truck with a drug dog, which alerted them that it had detected drugs in the driver’s seat. The police couldn’t find any drugs in the truck, so they ordered Young to drop his pants and underwear in the public parking lot to search him. Then, at 2am, they got a warrant for a body search at the local hospital, where Young was digitally penetrated and X-rayed, according to the complaint.

He was discharged at 4:30am, after cops failed to find contraband in his truck or hidden in his body. Later, Gila Medical Centre sent him a bill for $600.

Just a few months after Young’s encounter, some of the same officers stopped another man, David Eckert, in a Wal-Mart parking lot for failing to yield at a stop sign. The officers searched his car with a drug dog that alerted them to the smell of drugs. But they couldn’t find any contraband on Eckert or in his vehicle, so they obtained a warrant for a search of his body.

Over the course of 12 hours last January, Eckert was forced to receive an X-ray, CT scan, digital rectal exam, three enemas and a colonoscopy under anesthesia, according to his complaint filed in federal court this week. Eckert says the officers laughed at him at times while he was undergoing the procedures at Gila Regional Medical Centre, the same hospital where Young was taken.

Like Young, Eckert was also billed for the procedures — this time for $6,000.

“That’s unbelievable to me,” Kennedy, Eckert’s lawyer, told Yahoo News. Eckert had a previous conviction for methamphetamine possession; Young had no criminal record whatsoever, the lawyer added.

Young and Eckert are suing the officers and the county for violating their constitutional rights, including the right to be free from unreasonable search and seizures under the Fourth Amendment. They argue in a complaint filed in a federal court that Young was “raped under the colour of law” and that the officers’ conduct “shocks the conscience.”

The Hidalgo County Sherriff’s Office declined to comment on the cases, referring Yahoo News to the county’s attorney who did not return a request for comment.

“It’s something we’re quite concerned and often quite horrified at,” said Ezekial Edwards of the American Civil Liberties Union. “It’s hard to imagine when it would ever be appropriate, absent some personal threat of safety to the officer, for a court to allow these kinds of intrusions like anal cavity searches.”

Edwards linked the searches to the war on drugs and the nation’s record-breaking high incarceration rate, which he says leads some police into a mentality of trying to lock people up even when it means bending the rules.

Policies of “stop and frisk” in large metro areas like New York City have gained in popularity in recent years, meaning police are searching and stopping more people than ever before. The opportunities for abuse, then, are higher.

“You see an increase not to just stops and frisks but the lengths to which law enforcement will go to uncover evidence of drugs,” Edwards said.
