Flight Crew Rejected Takeoff
Airport
We were cleared for takeoff.  The aircraft that had just departed reported 'we may have hit something.'  Since it was night time and below 80 knots; I elected to abort the takeoff and wait for a runway inspection. Re-ran all the checklists and re-ran [Onboard Performance Tool] data. We departed as normal.
After the Captain set takeoff thrust; the Tower told the preceding aircraft (another carrier) to contact Departure. The other carrier acknowledged and said 'sorry to do this to ya; but we hit something on takeoff'. Tower said 'Company (us) did you hear that?' I stated 'what was it?' Other carrier said they didn't know what they hit. The Captain elected to reject the takeoff. It was at night; so we wouldn't be able to tell if it was a low risk strike like a bird; or something higher risk like a deer; alligator or aircraft part on the runway.
Air carrier flight crew executed an RTO at approximately 70 KTS when a preceding aircraft advised Tower that they had hit something on their takeoff roll.
