GAINESVILLE, Tex. -- Gainesville police arrested two men after north Texas authorities intercepted a package containing twenty pounds of marijuana.

Gainesville police were contacted Tuesday by the Fort Worth postal inspector who alerted them of a package containing drugs that was supposed to arrive in Gainesville on Wednesday. Authorities say the inspector saw the package was tagged as Express Mail, but had no person of contact. That tipped him off that the package could be suspicious.

A K-9 officer determined it was full of drugs, and Gainesville police arrested 32-year-old Pablo Palacios, Jr. and 19-year-old Brady Ratliff on Wednesday as they attempted to deliver those drugs.

Authorities say the two men were shocked police showed up with the package, and officers are glad they got to it first.

"They had actually left the residence and gotten into a vehicle when our officers pulled up, and then they saw the patrol car and they knew right then and when they spoke to our officers that they were caught," Gainesville Police Chief Steven Fleming said.

Both suspects have since bonded out but north Texas authorities say they will be on the look out for any suspicious packages in the area.
