Webb County Sheriff Martin Cuellar said police officers arrested the agent, Juan David Ortiz, early Saturday after a woman who claimed she had been abducted by Ortiz escaped half-clothed and sought help at a gas station in Laredo.
"We do consider this to be a serial killer", Webb County District Attorney Isidro Alaniz said.
The first murder took place September 3, authorities said.
Cueller did say that authorities have "very strong evidence" to link Ortiz to the crimes, and called him a "serial killer".
Police say he confessed to four killings, but refrain from revealing details of the attacks. Nationalities of the others are not yet known.
Having just spoken with Webb County Sheriff Martin Cuellar, there is no doubt in my mind that the heroic efforts of these four agencies have saved lives; they are to be commended.
A US Border Patrol agent has been arrested in the state of Texas on suspicion of killing four prostitutes, reports say.
"It's interesting that he would be observing and watching as law enforcement was looking for the killer, that he would be reporting to work every day like normal", Mr Alaniz said.
Authorities said that nearly had no doubt that Ortiz was behind the gruesome acts, with Webb County Sheriff Martin Cuelllar stating that police are in possession of "very strong evidence" implicating Ortiz. Federal prosecutors said the agent, Salvador Contreras, 50, sent child-porn images to an undercover agent whom Contreras believed was the mother of 8-year-old and 14-year-old girls. On Thursday a 42-year-old woman was found critically injured by the side of a highway and died in hospital.
Ortiz was approached by police at approximately 2 a.m. Saturday and initially fled troopers. All five women worked as prostitutes.
"I extend my condolences to the families of the victims during this hard time".
Ortiz was a 10-year veteran of the Border Patrol.
