FBI investigate ‘threats against Obama’

Officials say the FBI is looking into reports in Denver media outlets that a man under investigation for drug and weapons violations may have made threats against Barack Obama.

A US government official familiar with the investigation said: "It's premature to say that it was a valid threat."

Mr Obama is in Denver this week to accept the Democratic nomination for president.

Aurora Police Detective Marcus Dudley said that 28-year-old Tharin Robert Gartrell was arrested early Sunday in a routine traffic stop in the Denver suburb of Aurora.

Officials say he is being investigated for possible methamphetamine and firearms violations.
