Around 50 homes were evacuated in a security alert in north Belfast on Wednesday.
Police said Army Technical Officers examined the device at Silverstream Road and declared it to be an elaborate hoax.
People were out of their homes for around three hours on Wednesday morning and Ballysillan Leisure Centre was made available for those evacuated.
It was the third day of security alerts in the city.
A hoax alert shut the M1 motorway during rush hour on Monday morning.
Two pipe bombs were found in alerts in Belfast later that day.
On Tuesday a hoax caused the Alliance MP Naomi Long’s constituency office to be evacuated and part of the Upper Newtownards Road to be closed.
North Belfast DUP MLA William Humphrey said a local resident discovered the device before 9am in Silverstream Gardens and moved it to waste ground.
He said: “It is outrageous that this local community has been repeatedly targeted by people who care nothing for who suffers the consequences of their cowardly actions.
“The planting of these devices is causing massive disruption, anxiety and danger. I condemn those responsible without reservation.
“The police say they are keeping an open mind as to the motive. I call for an end to these incidents and urge anyone who can assist the police to identify those responsible to pass on whatever knowledge or suspicions they have.”
