Miguel Angel Iniguez, 41, was a supervisor for 28-year-old baggage handler Dicarlo Bennett, who pleaded not guilty Thursday to two counts of possession of a destructive device in a public place, a Los Angeles Police Department statement said. The statement said Iniguez, of Inglewood, was booked on suspicion of possession of a destructive device near an aircraft. He was being held on $500,000 bail. Both Iniguez and Bennett worked for Servisair, a leading global provider of aviation ground services. Bennett continues to be held on $1 million bail, but a bail review hearing will be held October 23. The court entered the not guilty pleas on his behalf. Bennett's defense attorney Ben Wasserman told reporters after the arraignment that Bennett was removing dry ice from a plane's holding area because he was told the vapors were dangerous to an animal being transported in the cargo hold.
