LAREDO, Texas -

Customs agents have busted a large load of liquid meth hidden in beer bottles.

The seizure happened at a border crossing in Laredo.

Agents say they found the drugs in those beer bottles inside a taxi coming across the border last week.

A Customs team got suspicious and decided to search the cab.

They say they checked those large bottles and found the liquid meth hidden inside.

The value of the drugs hasn't yet been determined, and Customs says it could vary depending on the purity of the meth and other factors.

Agents detained a Mexican man and woman riding in the taxi and turned them over to Immigration officials.
