(Reuters) – A man arrested by Texas police over his alleged involvement in the devastating data breach at No. 3 U.S. retail chain Target Corp last year was in fact picked up in a \street-level arrest\ unrelated to a broader federal investigation into the matter, a law enforcement official told Reuters. Earlier on Wednesday, USA Today and local TV station KVUE reported that Texas police arrested Guo Xing Chen, saying he was \involved in a large-scale credit breach believed to be in excess of $70 million according to investigators from the Target Corporation. \This appears to be strictly a street level arrest that is not tied to the larger breach investigation,\ the official, who is familiar with the Secret Service investigation into the Target breach, said on condition of anonymity. \These credit card numbers could have come from a variety of sources.\ Target spokeswoman Molly Snyder referred requests for comment to law enforcement officials.
