This is the moment an attention seeking cub annoyed his father once too often.
The cheeky cub can be seen tugging on his father’s mane, chewing on his fur and even smacking him on the end of the nose in a bid to entice him to play.
But while the father initially returned his son’s affections, he soon lost patience with the playful cub and snapped – baring his teeth at the startled cub.
I warned you, boy… Luke the lion makes it clear he has had enough of his son’s fun and games
The images were taken by photographer Paul Sutherland, 54, at the National Zoological Park in Washington, Columbia, US.
He said: ‘I’m connected with a number of people at the zoo and they invited me to come along when the lion cubs were born.
‘Having been an editorial photographer I like to create images which tell a story or send a message.
‘I spent a lot of time photographing the cubs, I went whenever I could. Every time the cubs came out there was a question mark over what they would do.

So much for my lie-in: Luke’s nap is a no-no as far as the youngster is concerned
Seriously, son, take the hint: Luke looks like he is enjoying a cuddle…but that out-stretched paw is getting ready to swipe
Right, that’s it! The cub takes a bite out of Luke’s chin… and he’s not happy about it
Fine, I’ll leave you alone! The cub retreats to safety… still with a look of mischief about it
