Aircraft
After the addition of thrust for T/O (takeoff) and selection of TO/GA (takeoff go-around) and N1 attaining T/O power; the aircraft was already rolling and had achieved approximately 15 knots of forward motion.  At that point we heard a very loud bang followed by a hard left yawing motion. The PF (Pilot Flying) immediately retarded the throttles to idle; and applied smooth breaking; which brought us to a complete stop.  We were angled left by about 30-40 degrees in relation to the center line of Runway 4; just prior to taxiway. I immediately informed ATC that we had stopped on the runway; the PF informed the PAX (passengers) to stay seated.  At that point we began to assess the situation. Initially we thought it was a blown tire or nose wheel steering issue. In that moment of assessing I noticed the #1 Engine Fail Caution illuminate in the #1 EGT Gauge. I informed the PF of the indication. It was the only indication we saw. No fire; no red lines only the engine failure alert caution. We reviewed the Rejected Takeoff Procedure; completed the QRH for Engine Failure. We then assessed the rolling and breaking capability of the aircraft and we found it to be normal.  We got clearance to exit the runway and return to the gate. As we pulled in to the gate; we remembered that we had not run an After Landing Checklist and quickly completed that; followed by the Parking Checklist. Then; the jetbridge malfunctioned and we had to wait until Airport Ops came to fix it. Once the jetbridge was attached I exited the aircraft to inspect Engine #1. I found the N1 fan blades and the stators directly behind them to be in a normal appearance. When I looked into the tailpipe of the turbine section; I found metal debris from the engine and both the aft fan blades and stators in front of them to be damaged and missing pieces. I hustled back to the Flight Deck to inform Ground Control that they needed to do a FOD check of the runway as we had; had and engine failure and that they needed to check for small engine parts.
First Officer reported engine failure on take off roll; resulting in engine damage and a return to the gate.
