One of America’s most wanted men arrested in north Wales after more than 20 years on the run had probably been there for a number of years, possibly using an alias, says an agency involved in his arrest.

Daniel Andreas San Diego, 46, was detained on Monday, Britain's National Crime Agency (NCA) told the BBC.

North Wales Police said he was in a remote location above Maenan in the Conwy valley in Conwy county.

America's Federal Bureau of Investigation (FBI) said it believed he was involved in the bombing of two office buildings in San Francisco, California, in 2003, and now faces extradition to the United States.

The FBI has accused him of being “an animal rights extremist”.

The first bombing was in August 2003 with two explosions an hour apart on the campus of a biotechnology company, followed by a nail bomb at a nutritional products company a month later, the FBI said.

He became the first "domestic terrorist" to be added to the agency's most wanted terrorist list, saying he “should be considered armed and dangerous”.

The FBI also said he was “skilled at sailing, and has travelled internationally”.

Michael J Heimbach, the FBI’s assistant director of the counterterrorism division, said the suspect had committed “domestic acts of terror planned out and possibly intended to take lives, destroy property and create economic hardship for the companies involved”.

It offered a reward of $250,000 (£199,000) for information leading to his arrest, saying he could have been living in Costa Rica.

According to reports, the agency’s last sighting of him was in 2003, when FBI agents were close in downtown San Francisco.

"He parked his car, got out of his vehicle and started walking down the street and if I'm not mistaken, he went into a Bart [train] station and that was the last time we've seen him," David Johnson, an FBI agent, said in 2013.

Andrew Black, a former FBI agent, said the case at the time was “of great interest” to the bureau.

“We had recently solved the Unabomber investigation, and bombings were a serious concern to the FBI and trying to solve them,” he told CBS news.

What is the FBI’s most wanted terrorist list?

The FBI’s most wanted terrorist list was created by then President George W Bush in October 2001, weeks after the 11 September attacks on New York City and Washington DC.

President Bush said the list would “shine the light of justice” on terrorists, who he said “try to operate in the shadows”.

“Terrorism has a face, and today we expose it for the world to see,” he said.

The first list had 22 people on it, including Osama bin Laden, who is believed to have ordered the 9/11 attacks, and was killed by US forces in Pakistan in 2011.

In 2013, Joanne Chesimard, a convicted killer who was a member of the Black Liberation Army also known as Assata Shakur, became the first woman to be added to the list.

There are currently 24 people on the list.

BBC Wales' Chris Dearden reports from the scene

It's north of Llanrwst as you work your way down the Conwy valley, a place called Maenan.

And just above, there's a house which is not too easy to get to.

There's no proper road access and basically Daniel Andreas San Diego was believed to be living there for some time.

I have been up there Wednesday afternoon and it's not an easy house to get to and locals said that this lone American had been living in the area certainly for a few years.

He kept himself to himself and one or two people recognised him from walking dogs.

But they did not know much about him and certainly not that he was one of the most wanted people on the FBI's terrorist list.
