A man who had worked as a road manager for an all-male striptease show has been arrested after a spate of bomb scares across the US.

Authorities say 56-year-old Cesar Sayoc - who was arrested in Florida on Friday - is the prime suspect in the case of a mail-bombing campaign aimed at high-profile US figures critical of President Donald Trump.

Recent days saw a dozen suspected live explosive devices sent to top Democrats, including former President Barack Obama and former Secretary of State Hillary Clinton, as well as individuals outspoken against Mr Trump, such as actor Robert De Niro.

None of these suspected explosives detonated, and no-one was injured.

On Friday, federal officials arrested Mr Sayoc outside an auto-parts store in Plantation, Florida, just north of Miami.

He was identified after his fingerprint was discovered on a package sent to Congresswoman Maxine Waters, officials say.

Authorities have yet to comment on a suspected motive, but Attorney General Jeff Sessions said "he appears to be partisan".

Who is he?

County records show Mr Sayoc, who is described as a white American, was born in Brooklyn, New York.

Mr Sayoc filed for bankruptcy in 2012, court records show, while he was living with his mother.

"Lives w/mom. Has no furniture," reads a hand-written note in his bankruptcy report.

In 1980, he spent three semesters as a student at Brevard College in North Carolina, a university spokeswoman told BBC News.

He did not graduate, the spokeswoman added.

High Point University, which he listed on his LinkedIn CV, told the BBC that he was never enrolled there as a student.

What is his criminal record?

Law enforcement officials said Mr Sayoc resides in Aventura, Florida.

In 2002, he was arrested for making a bomb threat in Miami-Dade County, and received one year of probation for the charge.

Mr Sayoc has a lengthy criminal record dating back to 1991 in Broward County, according to clerk records. He was arrested, aged 29, on a theft charge.

In May 2014, he pleaded guilty to charges of grand theft and battery arising from a shoplifting arrest at Macy's department store, court documents indicate.

During his one year of probation, he petitioned the court to be allowed to continue travelling, arguing that it was necessary for his job as a "road manager for a variety of travelling male revue shows".

Documents show he worked for "Chippendales, International Gold Productions, Cesar Palace Royale Burlesques show" and that he had the "potential to earn between $100-$200 a day.

"This has been significantly cut back since been [sic] on probation because of travel restrictions," his petition describes.

"His desire is to be able to continually tour," the petition says. It does not indicate whether his request was successful.

What are his politics?

He is a registered Republican, US media report.

Video footage also appears to show Mr Sayoc at President Trump's rallies in 2016 and 2017.

Social media accounts that appear to be owned by Mr Sayoc featured pro-Trump and anti-Democrat posts, including some tweets threatening the figures who received suspicious packages this week.

Twitter and Facebook have now suspended these accounts.

In the criminal complaint against Mr Sayoc, FBI Special Agent David Brown detailed some of his suspicious social media posts.

Some had misspellings consistent with the mailed packages, such as "Hilary" instead of "Hillary," and "Shultz" instead of "Schultz".

Mr Brown also pointed out a post dated 24 October - right after officials recovered the suspected pipe bomb addressed to George Soros - that was "critical of, among others, President Barack Obama and George Soros".

Locals in Aventura have said they had noticed his unusual white van driving around.

According to a Department of Justice charging document, the windows of his van was "covered with images including images critical of CNN".

"It struck me because of the crazy conspiratorial stickers covering the windows," one former resident, David Cypkin, told the New York Times after the arrest.

"It was unsettling, and also it seemed to be occupied. Sometimes the door would be ajar or a window would be open, which indicated to me that maybe somebody was living in the van," he continued.

The authorities impounded the vehicle on Friday.
