Narrative:

Approaching the airport; I was following a (other carrier) regional jet. I was told he was doing 130 knots eight miles from the field. I immediately started to slow but the spacing wasn't good; so tower told me s-turns to the north were approved; which I did. Spacing looked good so I continued. Tower told the regional jet to expedite off at D2 but didn't; and continued all the way down to the end of the runway. I was just about to round out when it was obvious the challenger wasn't going to clear the runway; so tower told me to go around. As I was climbing out; I heard tower tell a police helicopter to immediately descend. I looked out the windscreen and saw the helicopter right in front of me. It didn't look as though I was going to out climb him; so I immediately initiated a right hand turn to avoid. We never got an RA; but when we cleared the top of him; the TCAS read -200 feet. We continued around in a right traffic pattern and landed without incident.
