He's now filed a formal motion with the court to hold Norma in contempt for violating their custody order. In the legal doc -- obtained by TMZ -- Tyrese quotes from the custody order, which seems pretty clear -- "[Tyrese] shall have custody of Shayla every Tuesday with pick-up from school, and if no school, pick-up from [Norma's] residence at 10:00 a.m."
It's interesting -- Tyrese showed up Tuesday NIGHT -- not at 10 AM.
Sources close to Tyrese tell us ... he tried picking up his daughter at school -- but she wasn't there. We're told he repeatedly tried to contact Norma to pick up Shayla ... and finally went to Norma's house that night .. where he was turned away.
We're told Norma told Tyrese their daughter was sick and that's why she wouldn't let her go.
