Defendant Christopher Roby, 34, is being held in the Shelby County Jail.
The incidents occurred at around 7:30 p.m. on Jan. 30, 2018, when police responded to a mental consumer call at a residence in the 3200 block of Carrington Road near Park and South Greer.
Roby was on his porch and threw a fireworks-type object in the direction of officers. The object issued a burst of fire and then flamed out in the front yard. He eventually went inside the house and officers followed, using a Taser several times to no effect when Roby became combative and armed himself with a knife.
Several officers eventually wrestled him to the ground and handcuffed him, but one officer – a Crisis Intervention Team officer – was stabbed twice in the left side. He was taken to a hospital in critical condition, but survived his wounds.
Inside the house officers found several homemade pipe bombs.
