An illegal-immigrant mother of two was deported back to Mexico Thursday morning after her detention at a US immigration office in Phoenix sparked protests the night before, resulting in multiple arrests.

The lawyer for Guadalupe Garcia de Rayos and an immigrant advocacy group say they learned from Mexican diplomats in the US that she had been taken back to Mexico.

The Phoenix mother was in the country illegally and checked in Wednesday for what she thought was a routine meeting with Immigration, Customs and Enforcement officials. They then moved to deport her.

Immigration and Customs Enforcement spokeswoman Yasmeen Pitts O'Keefe confirmed in a statement that Garcia de Rayos was sent back to Mexico through the DeConcini Port of Entry in Nogales, Arizona, at 10am Thursday.

According to the statement, the deportation was carried out by federal agents in conjuncture with Mexican consular representatives.

ICE said that Garcia de Rayos had a prior felony conviction in Arizona for criminal impersonation and was the subject of a court-issued removal order, which was finalized in July 2013.

'Ms Garcia’s immigration case underwent review at multiple levels of immigration court system, including the Board of Immigration Appeals, and the judges held she did not have a legal basis to remain in the US,' the statement reads.

In the wake of the woman’s removal, ICE has tweeted out a series of messages expounding on its policies regarding the deportation of individuals.

'ICE will remove illegal aliens convicted of felony charges as ordered by an immigration judge,' one message read.

'ICE enforces our nation’s immigration laws in a professional manner,' read another tweet, followed by a third that stated: 'ICE targets convicted criminals and others who are illegally present in the United States.'

The latest message to have been posted on ICE's Twitter account Thursday said: 'ICE immigration enforcement actions target specific individuals according to the laws passed by congress.'

Phoenix Mayor Greg Stanton issued a statement addressing Garcia de Rayos' deportation, which he blasted as a 'travesty.'

'Last night's event show President Trump's mass deportation plan makes out country less safe,' Stanton said.

'Rather than tracking down violent criminals and drug dealers, ICE is spending its energy deporting a woman with two American children who has lived here for more than two decades and poses a threat to nobody.

'She has now been torn apart from her family,' Stanton's statement concluded.

On the eve of the woman's removal, dozens of activists blocked the gates surrounding the office near central Phoenix in an apparent effort to stop several vans and a bus from departing.

The activists said it was an attempt by President Donald Trump's administration to deport undocumented immigrants who had previously been shown leniency under the Obama administration.

ICE previously officials confirmed Garcia de Rayos was being detained as part of a removal order.

The 35-year-old resident of Arizona, who had been in the US for more than 20 years and has two American-born children, was arrested in 2008 when she was caught using a fake Social Security number during a raid on a water park where she worked.

One of the conditions of her punishment was to check in with the agency once a year. This time she was taken into custody.

On Wednesday, Garcia de Rayos apparently was in one of the vehicles, which are used to transport people in ICE custody to detention centers, or to Arizona's border with Mexico for deportation.

Police officers amassed at the facility as protesters continued to block access, chanting 'Justice!' and 'Power to the people, no one is illegal!'

Cops posted on Twitter that they arrested about seven protesters, but they added that most of the protesters were peaceful.

'Besides the few people engaged in criminal acts, most people out here are peaceful and exercising their rights properly,' police said. 'Everyone remains safe so far. Hoping for continued cooperation and no more criminal conduct.'

According to the Los Angeles Times, Garcia de Rayos arrived in the US aged 14 and was arrested on December 16, 2008 following a raid on the Golfland Sunsplash leisure center in Mesa, Arizona by the Maricopa County sheriff's department.

Garcia de Rayos was arrested in a major clampdown ordered by the hard-line sheriff of Maricopa County in Arizona Joe Arpaio who may be facing criminal charges himself over his controversial immigration patrols before he lost his position in January following an election

The raid, sanctioned by hard-line sheriff Joe Arpaio, targeted employers who knowingly employed undocumented migrants.

Authorities found Garcia de Rayos had been using a false Social Security number and she received a felony conviction.

In 2013, a court ordered her deportation.

Her arrest came just days after the Trump administration broadened regulations under which some people will be deported.

'We're living in a new era now, an era of war on immigrants,' Ms. Rayos's lawyer, Ray A. Ybarra Maldonado, said after leaving the building that houses the federal immigration agency.

The protests carried on late into the night and included several people who bound themselves to one of the vans while others sat in front of a closed gate, blocking anyone from leaving.

Police posted on Twitter that they arrested about seven protesters, but added that the demonstration was mainly peaceful.

'Besides the few people engaged in criminal acts, most people out here are peaceful and exercising their rights properly,' police said. 'Everyone remains safe so far. Hoping for continued cooperation and no more criminal conduct.'

By 1am today, less than two dozen protesters stood in the dark outside the building talking quietly, with just a handful of police looking on.

The protesters said they initially succeeded in stopping the vehicles from leaving, but said they later left the grounds by another exit. They didn't know if Garcia de Rayos had still been aboard.

Users on social media have had conflicting opinions on whether the round-up was justified

Puente Arizona, an immigrant advocacy group, said García de Rayos came to the US as a 14-year-old and now has two children. She was arrested on Wednesday while reporting to ICE, which she has done every six months since she was arrested nine years ago.

According to KTAR, Garcia de Rayos was arrested in 2008 during a workplace raid and was later convicted of felony identity theft for possessing false papers.

Despite her conviction, she was allowed to live in Arizona and checked in with ICE officials every six months.

In a tearful video interview uploaded before her detention, Garcia de Rayos and her family spoke of the trauma they face by the threat facing them.

She lives in Mesa with her husband and two teenage children, a daughter, Jacqueline, and a son, Angel.

A spokeswoman for ICE told MailOnline: 'Ms. Garcia De Rayos is currently being detained by U.S. Immigration and Customs Enforcement (ICE) based on a removal order issued by the Department of Justice's Executive Office for Immigration Review which became final in May 2013.

'Relevant databases indicate Ms. Garcia De Rayos has a prior felony conviction dating from March 2009 for criminal impersonation.'
