Gideon Kodua, Jordan Clark and Shayden Morris all scored in the opening 37 minutes as the Hatters all-but ended the contest by half-time.

Luton went ahead after eight minutes when Mads Andersen found Kodua, who spun away from his man and rifled into the bottom corner from 20 yards.

Town moved 2-0 in front after 20 minutes as Nahki Wells was clipped in the area by Jack Simpson for a penalty that Clark coolly converted.

And Luton added a third when Kodua’s cross was flicked on by Wells and an unmarked Morris tapped in at the back post.

Orient somehow failed to pull one back on the stroke of half-time when Sean Clare’s cross was turned over from six yards by Dominic Ballard.

A much quieter second period saw Cohen Bramall’s cross met by Kodua and Clark’s attempt repelled by Orient goalkeeper Tommy Simkin.

Town defender Teden Mengi was forced to clear off the line, while Josh Keeley saved well from Ollie O’Neill late on.
