Lawsuit: Des Moines officer, charged with domestic abuse, also punched groom in 2011

  
DES MOINES, Iowa — A Des Moines police officer charged with domestic abuse is facing a lawsuit alleging he repeatedly punched a suspect who was on the ground.
The Des Moines Register (http://dmreg.co/KjQ7dl ) reports that John Twombly alleges he was assaulted by officer Cody Grimes at Twombly's 2011 wedding reception.
A spokesman says Des Moines police investigated but found no wrongdoing by Grimes.
Grimes is charged with domestic abuse causing injury after an altercation with his ex-girlfriend.
Twombly's lawsuit alleges, Twombly was involved in an altercation with a groomsman at the reception. An off-duty officer who was providing security called Grimes for backup.
The lawsuit claims Grimes threw Twombly against a wall and took him to the floor, held his head and punched him.
Grimes admits he struck Twombly but says it was self-defense.
