In a post on social media the PSNI said Army bomb experts attended the scene. The suspected weapon has been taken away for examination.
On Tuesday, police said a series of security alerts following the bombing were designed to "frustrate" their enquiries.
Three alerts - triggered when two vehicles were hijacked by masked men and a delivery van abandoned - ended in the early hours of Tuesday morning.
The alerts came less than 48 hours after a bomb exploded in a car outside the courthouse.
Police have released five men who were arrested following the bomb attack.
