ARLINGTON -- One man was arrested after police seized over 70,000 pills and more than 20 pounds of marijuana inside an Arlington apartment complex.

According to a search warrant affidavit, Arlington Police responded to a drug-related call at a complex on the 1700 block of Saddle Creek Circle on Tuesday.

A maintenance worker had discovered a “large amount of green leafy substance,” later determined to be marijuana, during an inspection related to storm damage, according to a search warrant affidavit.

The worker took a photo of the marijuana and sent it to the apartment manager, the affidavit reads.

An Arlington officer also smelled marijuana coming from a single unit of the three-story apartment complex when attempting to make contact with the tenant.

When a search warrant was granted, officers found 22 pounds of marijuana and at least 72,000 pills believed to be Xanax in an apartment belonging to 24-year-old Duc Chi Ta.

Arlington police said it was the largest known pill bust in department history.

Four handguns and "lots of cash" were also seized from the apartment.

Lt. Chris Cook said that had Ta simply been aware his complex was doing maintenance, as advertised throughout the property, he probably wouldn't be in trouble.

"This was kind of luck," Cook said. "He had the maintenance letter crumbled up in his trash can."

Ta was arrested on two felony drug charges -- one for possession of marijuana between five and 50 pounds, and another for possession of a controlled substance with intent to deliver.

He was booked into jail on $50,000 bond, but has since bonded out, police said.
