It is understood Michael Higdon was released from police custody earlier today.
He is the Scottish Premier League's top scorer this year, having netted 26 goals for Stuart McCall's side.
The player, who arrived from St Mirren in the summer of 2011, now holds Motherwell's post-war record for league goals scored.
Higdon has described the season as the "best of his career" and credited his success to "confidence, playing in a good team and having a manager who believes in me".
