Pocatello firefighters blocked traffic around a ruptured natural gas line at 1550 Yellowstone.
Investigators said a riding lawn mower swept over a small natural gas line and caused a minor leak. The area was closed as a precaution. A private company was mowing a vacant lot in the Bel Air Estates mobile home park.
The broken pipe was traced back to a main junction and it was shut off for repairs.
No one was hurt. Emergency crews completed their work around 4:30 p.m.
