By Mark Hosenball WASHINGTON (Reuters) – The U.S. Secret Service said on Tuesday it was checking for links between the recent hacking of consumer data from Target Corp and the weekend arrest of two Mexicans who tried to enter the United States at a Texas border crossing with a cache of fraudulent credit cards. But other law enforcement sources said it was not clear whether there was a link between the Target data breach and the arrests, which occurred at the U.S. border crossing at McAllen, Texas. Edwin Donovan, a spokesman for the Secret Service in Washington D.C., confirmed that the agency was looking for any connection between Target data breach and the two Mexicans. Target has said a breach of its networks during the busy holiday shopping period resulted in the theft of about 40 million credit and debit card records and 70 million other records with customer information such as addresses and telephone numbers.
