WEST UNION (AP) - Three men have been arrested and charged with 27 fishing violations after using beer cans to catch trout from a northeastern Iowa creek.

Authorities say an off-duty Fayette County deputy noticed suspicious fishing activity at Glovers Creek trout stream earlier this week. He called the Iowa Department of Natural Resources.

DNR officials accuse the three men of illegally tying fishing lines to empty beer cans, then dragging the cans with the catch to shore. Authorities seized the trout, illegal fishing lines, rods and reels, beer and a van with Wisconsin license plates.

Authorities say the men were not U.S. citizens and that immigration officials were notified.

Officials say the men had been living in Postville.
