Teenagers are being warned about a new app designed to help them make new friends, which is being misused by adults sharing sexual content.

Monkey allows strangers to video chat for 10 seconds.

Victoria Derbyshire reporter Amber Haque encountered people lying about their age, making sexual remarks, sharing pornography and masturbating.

In a statement, Monkey said: "Safety is our primary concern... we may ban users who have violated our community guidelines."
