The fourth suspect in an armed robbery of an Uber driver earlier this year in Jupiter is being held without bond.
Deon Robinson, 20, of Riviera Beach went before a judge Monday morning after he was arrested Sunday.

His co-defendants, Raequan Haywood and Kyle Williams, were arrested in May. Lenardis Bother, 15, is scheduled for a plea conference in October.
Law enforcement said the Haywood and Williams were arrested after they almost hit two federal agents driving near them.
The judge said Monday that Robinson's actions are punishable up to life in prison. He is charged with robbery with a firearm and carjacking with a firearm.
