POCATELLO, Idaho -

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.
