A mysterious investor out of London has asked a bankruptcy judge in Delaware to stop the sale of EV startup Canoo’s assets to its CEO, calling it a “flawed” process.

Charles Garson, a UK-based investor with no obvious ties to the EV startup, offered $20 million for Canoo’s assets, according to a filing. A lawyer representing Garson filed a motion Friday to vacate the sale, claiming he presented a “far superior offer” to that of Canoo CEO Anthony Aquila, who bid just $4 million in cash for the assets. (Aquila’s bid also includes the extinguishment of around $11 million in loans Canoo owes to his own financial firm.)
