He asked if they had a permit before calling the police, a move that prompted Samantha and her five friends – her husband Dean, friends Deborah and Warren and daughters in law Ella and Emily – to scarper from the park.
Samantha, who runs a childminding business, said: “We were having a wonderful time and kids were loving it, then we found out some idiot had phoned the police, I couldn’t believe it.
“We were just trying to cheer up some kids up after such a miserable year, we weren’t hurting anyone.
“We had no choice but to leave because we didn’t want to risk getting arrested – although watching the police chase six dinosaurs would have been funny.”
Samantha had posted her plan on Facebook, encouraging friends to come along and watch.
To ensure social distancing, she roped in her sons Noah and Harry to make sure no one came to close.
But, nine minutes into the event, a man came and spoke to Harry and Noah and asking questions, such as “Have you got a permit?”– to which the answer was no.
“And after that, he rang the police, which when we knew we had to leave,” Samantha said.
“It was such a shame because the kids haven’t had much to do over the past 12 months, which is why we wanted to go out in the outfits.”
Samantha said the whole affair made her “so angry” she couldn’t sleep that evening.
“When I woke up on Sunday I said: that’s it I’m going back out.”
