(AP/Meredith) -- The daughter of a Mexican couple who was detained trying to visit their pregnant daughter at an Army base in upstate New York are begging immigration officials to set the couple free.
Concepción and Margarito Silva were arrested by federal immigration officials on July 4 after they arrived at Fort Drum for a holiday visit with their daughter and their enlisted son-in-law.
The couple appears to have attracted the attention of base security personnel after they presented New York City-issued identification cards at the fort's gate.
Guards asked to see a different form of ID. When they presented Mexican passports, military police contacted Customs and Border Patrol agents, who detained them.
Their daughter, Perla Silva, said Wednesday that her mother should be released because she has a serious heart condition that requires medication.
In a statement, the U.S. Customs and Border Patrol said the couple admitted to being illegally present in the United States and were charged with being present in the United States without admission or parole. CBP also said both individuals had their medications with them and were allowed to take them when needed.
