Unsure on how our Suspicious Activity Portal works?
It’s a portal we’ve launched to allow members of the public to send us smart doorbell or home CCTV footage which shows someone acting suspiciously. We launched this system early last year and we’ve already had a number of success stories in which we have been able to identify, arrest and charge individuals for various offences.
If you notice anything suspicious in your local area, please report it immediately through our portal. Even if you think it’s nothing, your footage can help us identify suspects in the long run.
