Police in Los Angeles have detained a "person of interest" in their continuing search for a serial arsonist.
The announcement came after 12 more suspected fires were set early Monday.
The developments in the case came after officials released DVDs containing video of a man suspected of setting a string of fires in the city.
A total of 43 suspicious fires have been lit in the LA area since last Thursday. Most of the fires were set in parked cars.
Police describe the suspect as an older white male with a receding hairline and a shoulder-length ponytail.
The man was seen on video Saturday after emerging on foot from an underground parking structure near the scene of a car fire.
"It's still too early to say whether or not this person has any direct correlation with the number of fires that we've been responding to this evening," LA Fire Dep. spokesman Capt. Moore said.
No arrests had been made.
Local authorities are offering a $60,000 reward for information leading to an arrest in the case.
