Narrative:

Aircraft X VFR inbound from south; landing tvc. Local recommends aircraft X to alter course to fly a northeast heading to deconflict an impending IFR departure off runway 18. Aircraft Y calls ready; IFR departure off runway 18. ZMP releases aircraft Y. Standard release is runway heading to climb and maintain 3000 MSL. Local reasoned that this would allow the two aircraft to safely pass each other. After frequency change to ZMP; aircraft X was issued traffic on the departing aircraft Y on the climbout. Aircraft X pilot started descent and looked for aircraft Y traffic. Radar indicated aircraft X at 2300 MSL as aircraft Y turned towards the helicopter on a converging course; altitude indicated 2500 MSL. Aircraft Y was clearly still within class delta airspace when turn took place. When queried aircraft X pilot said he had aircraft Y in sight. It's really very simple. Follow the procedures that are already in place. That is the basis for actions on both the tower side as well as the radar side of the relationship. Besides that; why as a radar controller would you turn your aircraft towards a target you could avoid in another 1 or 2 miles? In speaking with the aircraft X pilot on the telephone; he said once he got the aircraft Y in sight; that he estimated the vertical distance between the two aircraft near 2-300 ft.

Title: TVC Controller reported a NMAC between a helicopter and a fixed wing aircraft due to a heading change from the Local Controller and the Center Controller. Reporter stated there is a procedure in place already to avoid this problem between Local and Center.
