People wanted on various outstanding charges were arrested as they tried to enter the country through the U.S. Port of Entry at San Luis, Ariz., over the weekend.

 They were arrested in unrelated cases after routine computer checks done by port officers found warrants for their arrests, CBP said.

  "The technology capabilities of our computer systems provide us the ability to receive information from other law enforcements agencies," said Port Director William K. Brooks. "This partnership allows us to catch those with criminal records who are supposed to be behind bars."

  The first arrest came Friday when a CBP officer screening travelers did a computer check of a passenger of a vehicle entering the country from Mexico. The query revealed the 29-year-old U.S. man had outstanding warrants for a sex offense in Puerto Rico and for a fraud charge from Washington state.

  The man was arrested and turned over to the U.S. Marshals Service for further investigation and processing, CBP said.

  Also Friday, a CBP officer screening travelers found a 42-year old U.S. citizen man was traveling with another person who had previously secured an order of protection against him, CBP said.

  The man was arrested and turned over to the San Luis Police Department.

  On Saturday, officers arrested a 25-year-old man who had been charged with contempt of court. He was arrested and turned over to San Luis police.

  Also Saturday, a 45-year-old Mexican man was arrested after a computer check discovered a warrant had been issued for his arrest for failure to appeal in court on a theft charge. He was turned over to San Luis police.

  The names of the four and other details were not immediately available.
