Pokémon Go fans are being urged to be precautious while searching for the characters in Sunderland and South Tyneside.
The phenomenon of Pokémon Go has swept the nation turning even the North East into a Pokémon zoo.
The app sends the messages with all possible locations dragging the fans out, but some of those locations might put the players in danger.
Northumbria Police encourages Pokemon Go fans to avoid getting too close dangerous edges and not to put themselves at necessary risk.
Southern Area Command Chief Inspector Paul Milner said:
“Pokémon Go is a fantastic game, it gets people out and about visiting new places and is great fun and I want to make it clear that the last thing we want to do is spoil that fun for people.
“However, we are mindful that the school holidays are coming up and we know children will be playing the game and want to make sure they are safe.
“We’ve been made aware that some children may be putting themselves at danger by getting too close to cliff edges and we just want to remind both children and parents to make sure they keep a safe distance from dangerous edges.
“I’ve been reliably informed that you can still catch Pokémon from quite a distance and while they might not be as close as they would like it is important children are not putting themselves in danger.”
The NSPCC has released a guide for parents to keep young Pokemon go fans safe that can be found here.
