A suspected arson fire damaged a residential cottage in North Park Wednesday and left a 57-year-old woman injured.

The blaze in the 4400 block of Utah Street erupted shortly before 10 a.m., according to the San Diego Fire-Rescue Department.

While extinguishing the flames, firefighters found the woman and pulled her out of the burning residence, the agency reported. Paramedics took her to UCSD Medical Center in Hillcrest for treatment of burns and smoke inhalation. The severity of her injuries was unclear.

It took crews about 10 minutes to extinguish the blaze, which caused an estimated $50,000 worth of damage to the structure and destroyed about $15,000 worth of contents, according to the SDFRD.

Investigators with the San Diego Metro Arson Strike Team determined that the fire appeared to have been deliberately set, the fire department reported. No suspects had been identified as of late afternoon.
