A convicted murderer who had been living in the United States under a false identity has been arrested in Houston, Texas, according to U.S. media reports.

The man, who is a national of the Caribbean island of Dominica, was originally sentenced to 45 years in prison but was mistakenly released after being wrongly identified as a U.S. citizen. He had been living in the country illegally.

U.S. Border Patrol’s Laredo Sector said he is now back in custody and faces deportation proceedings, adding that his arrest has helped improve public safety.
