An unpaid restaurant bill led to gunfire in downtown Walnut Creek on Sunday night, according to city officials.

Police were still looking for the suspect and had not made any arrests by Tuesday morning.

According to city spokeswoman, Betsy Burkhart, the gunfire happened after a couple left a dinner at Modern China Cafe in the 1500 block of N. Main Street around 8:30 p.m. without paying.

The owner chased after the couple as they headed to their car across the street, Burkhart said. He confronted them, and the man eventually paid before getting into the passenger side of a black Kia.

The car drove away, and as it did, the man pulled out a gun and fired into the air at least three times, she said.

Nobody was injured in the gunfire.

Police have not made a statement about the shooting, and there was no description of the couple.
