Chicago Bears receiver Sam Hurd was arrested in Chicago on federal drug charges on Wednesday night, and the criminal complaint against him describes Hurd as regularly dealing large amounts of drugs in Chicago.

Hurd allegedly attempted to purchase cocaine and marijuana from a supplier in North Texas, the location of where the case will be adjudicated. He was arrested by undercover agents at a Chicago steakhouse Wednesday night and was due to appear in federal court in Chicago Thursday to face a charge that he did "possess with intent to distribute 500 grams or more" of cocaine.

"We are aware of Sam's arrest and are continuing to gather details surrounding it," the Bears said in a statement. "We are disappointed whenever these circumstances arise. We will deal with them appropriately once we have all the information."

The investigation into Hurd's attempt to buy large amounts of cocaine and marijuana began in July 2011 when he was still a member of the Dallas Cowboys and concluded when he personally met with a confidential informant at a restaurant on West Bryn Mawr Avenue in Chicago Wednesday.

At that meeting, Hurd told the informant that he wanted to buy "five to 10 kilograms of cocaine and 1,000 pounds of marijuana per week for distribution in the Chicago area," according to the complaint.

Hurd allegedly negotiated to pay $25,000 per kilogram for the cocaine and $450 per pound for the marijuana. The complaint says that Hurd "further stated that he and another co-conspirator currently distribute four kilograms of cocaine per week in the Chicago area, but that the supplier could not supply him with enough quantity."

After they agreed on a price, the undercover agent gave Hurd a kilogram of cocaine, according to the complaint. Hurd told the agent that he plays for the Bears and would get out of practice at 5:30 p.m., at which time he would make arrangements to pay for the drugs. According to the complaint, Hurd then took the drugs and got in his car. He was promptly arrested.

Hurd hit authorities' radar in July when a confidential informant told police that a man was attempting to obtain four kilograms of cocaine for an unknown buyer in the Dallas area. That man was later stopped by police with $88,000 in a canvas bag. He said that the car and the money belonged to Hurd. Police confiscated the money, and Hurd later contacted authorities trying to get the money back.

Hurd was interviewed by police and admitted that he owned the car and had taken the money out of the bank, but authorities found that bank records did not match the amount.

Then in August 2011 text messages and cellular phone records from a number used by Hurd showed up in relation to four individuals who were detained in California with currency, narcotics and weapons. The complaint states that the text message content "appeared to be consistent with narcotics trafficking and possible money laundering."

In December the confidential informant told the co-conspirator that he would have to meet Hurd to "discuss future business." That led to the meeting and arrest in Chicago Wednesday.

A free-agent acquisition by the Bears from the Dallas Cowboys in July, Hurd has played in 12 games this season primarily as a special-teams contributor. As a receiver, Hurd has posted eight catches for 109 yards.

"I think everyone is (shocked)," Bears linebacker Lance Briggs said. "Nice guy. Sam is a nice guy. Well liked, well liked in the locker room. He was a guy we were just all getting to know.

"You hate to see this happen to anyone. We all make mistakes, but like I said, it's just sad to see."

Brian Urlacher also said Hurd seemed to be a good teammate.

"Sad for him," Urlacher said. "Not sure what is going on. But never want to hear something like this happen to one of your teammates.

"Good teammate. That's what I know of him. He comes to work every day and works hard. Outside of here, I don't know him very well, but he comes to work every day and practices hard and plays hard. That's all I know of him. He's a friendly guy. Always been really friendly. Says 'Hi' in the hallway every time you walk by him and I walk past him 10 times a day in the hallway and he still says 'Hi' every time. He's a good guy, from what I know of him from being in the building."
