A statement posted on the ALF Website states that the group entered the farm, released the mink and destroyed all breeding records. It states they destroyed an electrical fence, vandalized trucks and equipment and cut about 100 holes in the perimeter fence.

Juan Becerra, spokesman for the the FBI's Salt Lake City office, said his bureau was assisting local detectives, but that it was too early in the investigation to speculate on "subjects or suspects" involved.

The FBI and Kaysville police began conducting interviews into the break-in but have not identified any group or person involved, they said. The Davis County Sheriff's Office is handling animal control.

Kaysville Capt. Paul Miya said Monday afternoon that there were no suspects whatsoever. After hearing of the press release he said, "It's something we'll look into, but I don't give [ALF] a lot of credit for what they say."

Lt. Brad Wilcox with the Davis County Sheriff's Office said all but about 500 of the 6,000 minks released from Lodder Fur Farm had been recovered by Monday. About 500 of the mink died of heat exhaustion Sunday.

The break-in was the second where mink have been released in Utah recently and where the ALF has taken credit. The other case occurred Aug. 19 in South Jordan and is still under investigating. The culprits there destroyed breeding records, and many of the mink died from stress or being hit by cars.

Miya said his department has not yet contacted South Jordan to see if there are any similarities between the two break-ins.

After the South Jordan incident, the media office for the Animal Liberation Front posted a statement from "a local soldier out of Utah" saying that 300 minks had been released.

Meanwhile, in the Kaysville area, Wilcox said the Davis County's Sheriff's Office and animal control have been inundated with calls from residents in the west part of Kaysville and in Farmington west of Interstate 15 who have reported mink showing up in their yards.

Davis County animal control field supervisor, Bryan Smith, said he has received calls from as far away as 7 miles from the farm, which is near Shepard Lane and Sunset Drive.

"All day today, we've been getting calls on them," he said.

At least two animal control officers have been fielding those calls and catching the mink with nets. At least 40 were rounded-up Sunday and 19 were captured Monday morning.

So far, there are no reports that any mink have run onto Interstate 15 and been struck by traffic, said Wilcox, adding that the farm is nearly three miles from the freeway. The mink also would have had to cross three rail tracks to get to the freeway, since FrontRunner crosses the area, Wilcox said.

"They're real fragile animals," Wilcox said. "They shouldn't be in this area naturally."

Anyone who finds mink in their yard should call Davis County Animal Services at 801-444-2200.
