Aston Villa's Lucas Digne and Matty Cash were both struck with bottles after they went 1-0 up against Everton at Goodison Park.
The French international returns to face his former club for the first time since his departure earlier in the window, but there were unsavoury scenes in the aftermath of Villa's opener.
In added time of the first half, Digne stepped up to take a corner for his new club and was booed by Everton supporters as he whipped a dangerous ball into the box.
