Lawrence firefighters responded to a fire call at Royal Crest Lanes, 933 Iowa, at 7:08 p.m. Monday evening, when a fire was discovered in the rear of the building. A second alarm was sounded because of excessive outdoor temperatures and the high heat index, a news release from Lawrence-Douglas County Fire & Medical said.

The fire was declared under control by 7:42 p.m.

Patrons and employees of the bowling alley were evacuated safely, and no one was injured.

An investigation is under way to determine the cause of the fire. A damage estimate has yet to be determined.
