A Coralville man awaiting trial on robbery and stabbing charges has been arrested on unrelated drug charges.

A Coralville Police officer reports seeing 18-year-old John Greb of Wind Ridge Drive driving his motorcycle near 1st Avenue and Oakdale Road just before 4pm Wednesday. Greb’s license is revoked until March of 2020 for an OWI test failure. A search of Greb’s person after a traffic stop near Dubuque Street and West Overlook Road turned up a medicine bottle filled with a green leafy substance believed to be marijuana.

Greb is charged with Driving While Revoked and Possession of a Controlled Substance. If convicted on both charges, he faces a maximum of two years in prison.

Greb is awaiting a September 5th trial on charges of 1st Degree Robbery, Willful Injury Causing Bodily Injury, Interference with Official Acts and Possession of Drug Paraphernalia stemming from an incident at Coral Ridge Mall.

Coralville Police say Greb used a knife to assault and injure a security guard during a robbery attempt at Target just before 5:30pm on April 20th.

Greb was eventually apprehended on the nearby pedestrian tunnel under Interstate 80 after a brief foot chase. He was covered in blood, and was found in possession of a bloody knife. A search of Greb’s person turned up several baggies containing Adderall, as well as a pipe with residue believed to be used for smoking marijuana.

If convicted on all charges relating to the robbery, Greb faces a maximum of over 30 years in prison.
