A "frustrated" jobseeker from Davao caused a brownout for more than four hours in a town in Bulacan province late Tuesday night, after climbing a 130-foot tower of the National Transmission Co.

Radio dzBB reported that the jobseeker, initially identified as Roy Villar, 20, forced TransCo personnel to cut off power to the 230-kilovolt tower he climbed in Turo village in Bocaue.

Police are now examining Villar for possible signs of "mental problems" after he eventually decided to climb down from the tower past 11 p.m., more than eight hours after he climbed it.

Initial investigation showed Villar climbed the tower at 3 p.m. Tuesday, after four days of walking all the way from Port Area in Manila.

A separate report on dzXL radio reported that Villar said he arrived in Manila four days earlier, looking for a job. But he said he could not find his "recruiter" at the Port Area.

He climbed the Transco tower at 3 p.m. Tuesday. Transco personnel cut off power to the 230-kilovolt tower at 7 p.m. to prevent him from being electrocuted.

Three Transco linemen went up the tower at 9 p.m. to convince him to climb down, but it was only past 11 p.m. that he did so.

Villar was initially described as 25 to 30 years old, stocky, 5'5" to 5'6" tall, and wearing a yellowing T-shirt and black short pants.

Rescue workers at the site for more than six hours said Villar had made no demands and had so far declined offers of food.
