Narrative:
Air carrier Y, B737, was being vectored behind air carrier X, E145. Both aircraft were slowed to 210 KTS because of approach control's request. I diverted my attention to deal with other aircraft, including an aircraft who had called on my frequency who wasn't supposed to. When I realized that the vector on air carrier Y would be insufficient, I asked cle approach to descend the other aircraft X out of the way.

Title: ZOB CTLR COORDINATES WITH CLE IN AN ATTEMPT TO RESOLVE AN ACFT OVERTAKE CTL EVENT BTWN 2 ACR'S.
Narrative: ACR Y, B737, WAS BEING VECTORED BEHIND ACR X, E145. BOTH ACFT WERE SLOWED TO 210 KTS BECAUSE OF APCH CTL'S REQUEST. I DIVERTED MY ATTN TO DEAL WITH OTHER ACFT, INCLUDING AN ACFT WHO HAD CALLED ON MY FREQ WHO WASN'T SUPPOSED TO. WHEN I REALIZED THAT THE VECTOR ON ACR Y WOULD BE INSUFFICIENT, I ASKED CLE APCH TO DSND THE OTHER ACFT X OUT OF THE WAY.
