RBS Citizens, better known as Citizens Bank, has sued Curt Schilling to recover $2.4 million in loans it made to the retired Red Sox star’s bankrupt video game company.

Providence-based RBS Citizens is among the first creditors seeking to hold Schilling personally responsible for debts incurred by 38 Studios LLC, which filed for Chapter 7 bankruptcy protection last week, the first step in liquidating the company. Most creditors like RBS Citizens have little hope of recovering their money from 38 Studios; it reported owing more than $150 million but has less than $22 million in assets.
