Two young girls ran screaming from a Liverpool park after a man dressed as a clown reportedly jumped out from behind a bush and chased them.
The two 12-year-olds were in Walton Hall Park when a man in a frightening clown outfit emerged in front of them and started hysterically laughing, one of the girl's mothers said.
Marissa Roberts said her daughter and a friend were in the park at about 9pm on Saturday night when the incident happened.
Merseyside Police said they are investigating reports of the incident and want witnesses to come forward.
Marissa said her daughter and friend visited the beauty spot to film videos on Saturday, before seeing the creepy figure.
She said: "They heard noises from the bushes, then a man in a clown outfit jumped out and said 'Hi'.
"My daughter said he laughed, like [the clowns] from the movies.
"My daughter rang me screaming. I ran [to them] and they were screaming, and they said he ran back after hearing her on the phone."
The force said it received reports a man in a black and white clown outfit was holding a "shiny object", which Marissa said her daughter saw too.
Marissa added the girls have since been scared to return to the park, despite her trying to reassure them.
A spokeswoman for Merseyside Police said: "We can confirm we were contacted following reports of suspicious circumstances in Walton Hall park.
"A report was made at 9.30pm on Saturday 8 th August that a man wearing a black and white ‘clown’ suit had jumped out of bushes in front of two young girls before chasing them out of the park.
