(CNN) A 45-year old Mexican man who was taken into custody by border patrol agents in the Rio Grande Valley of Texas earlier this month died Monday, US Customs and Border Protection said.

CBP says the man was detained on February 2 after crossing the border illegally. He initially asked for medical attention from the Roma Police Department. He was transported to the regional medical center and then cleared to travel to the Rio Grande City Border Patrol Station.

The next day, he again sought medical attention and was transferred to McAllen Medical Center in McAllen, Texas, where he died earlier today.

The man was initially diagnosed with cirrhosis of the liver and congestive heart failure, though the official cause of death is not known, according to CBP. He remained at McAllen Medical Center until his death.

CBP did not provide additional details such as the man's name.
