It is imperative that police act quickly to apprehend these dangerous, reckless criminals before someone else is hurt."One of the biggest issues in this community is fear of crime. This incident will have only increased that anxiety among residents. I would encourage anyone who may have seen or heard anything suspicious to report it to the PSNI at Antrim Road police station and help bring this gang to justice."North Belfast DUP MLA Nelson McCausland has also appealed for full co-operation with the police."This was a particularly vicious, nasty and brutal aggravated burglary. Those responsible have caused physical injury to innocent people in pursuit of their selfish criminal gain."This innocent family have been put through a terrifying and traumatic ordeal. The entire community is outraged and disgusted by this crime and is unified in calling for the perpetrators to be brought to justice."Sinn Féin councillor Mary Ellen Campbell said that anyone with any information, no matter how small, needs to come forward as soon as possible.
