Gas leak traced to valve accidentally left open

Emergency crews responded to a northwest Omaha neighborhood Friday evening on a report of a potentially dangerous gas leak.

Investigators say a three-block area around 156th Avenue north of Cuming Street was blocked off.

A 6 News crew noticed a construction project underway along 156th Street.

We're told a senior citizen had left his home and left the fireplace gas valve on.

The scene was declared safe around 8 p.m.
