The actor, who plays unlucky-in-love student Jamil Fadel, has been with the show for almost a year - first appearing in online spinoff Hollyoaks Freshers before moving over to the main programme last September.
Speculation over the character's future began today when fans noticed that he does not feature in the updated Hollyoaks titles, which make their screen debut in tomorrow night's E4 'first look' airing.
Asked about Jamil's absence on Twitter this afternoon, Malik replied: "It's because due to my certain concerns, I have decided to leave Hollyoaks this year at the end of my contract."
Digital Spy understands that Jamil will depart screens in the autumn.
