Police are investigating the theft of about $70,000 worth of bull semen from a farm in southern Minnesota.

Mower County Sheriff Terese Amazi says a LeRoy man reported Tuesday that a storage canister with vials of bull semen was taken from his unlocked barn.

The theft happened sometime between April 1 and 7. The man said the only time he and his hired hand were away from the farm was on Easter Sunday.

The Austin Daily Herald reports the canister was worth about $500, and the vials of semen were worth from $300 to $1,500 apiece.

Police have no suspects.
