It is thought the device, which was spotted on the Ballymagarry Road on Monday, fell off after being strapped to a car.
It is believed a member of the PSNI or other security forces was the intended target.
Police set out to speak with local residents and drivers in the area during their investigation to determine who was behind the attempted attack.
A PSNI spokesperson said: "Officers are particularly keen to hear from anyone who may have travelled along the Ballymagarry Road anytime between Wednesday 7 November and Saturday 10 November and who may recall seeing anything suspicious or unusual lying on the road."
They have also appealed for anyone who may have noticed suspicious behaviour on the road or in nearby housing developments to contact them.
