A brush fire Monday in San Ysidro burned about a quarter-acre and briefly threatened an apartment complex, according to the San Diego Fire-Rescue Department.

The fire that started in a homeless encampment and spread to nearby vegetation was first reported just after 8:45 a.m., at San Ysidro Boulevard and Cottonwood Road, Fire-Rescue officials said.

Firefighters were able to contain the blaze shortly after 9 a.m.

A three-story apartment complex being threatened by the fire was evacuated but was not damaged. There were no injuries reported.

Fire-Rescue was assisted by fire department crews from the cities of Chula Vista, Coronado, National City and Poway.

There have been over two dozen fires along Interstate 5 in this area over the past two months, and an alleged arsonist was arrested last week.
