Suspect under arrest in deadly NYC subway attack

A man suspected of abruptly pulling a gun and killing a stranger on a New York City subway train has been arrested. But police say they don't yet know what motivated the apparently unprovoked attack.

Andrew Abdullah was taken into custody on Tuesday; hours after authorities posted his name and photo on social media and implored the public to help find him. The 25-year-old is expected to face a murder charge in the death of 48-year-old Daniel Enriquez. Enriquez was shot to death while heading to brunch Sunday morning.
