( CNN ) An anonymous letter bitterly insulting African-American officers was recently found in mailboxes at a Connecticut police station . It was written on official letterhead , CNN affiliate WFSB reported . It starts out with the words `` WHITE POWER '' in capital letters . And it contains a line that reads , `` These Black Officers belong in the toilet . '' It ends at the bottom with a repeat of the words `` WHITE POWER . '' The letter was flagged to authorities by a police organization for minority officers , The Bridgeport Guardians . Though decidedly racist against all black officers , the letter singles out one in particular -- Clive Higgins , who a jury recently acquitted of using undue force in the kicking of a detained man lying at the feet of Higgins . Two other officers , one Hispanic and one white , were also involved . Those men -- Elson Morales and Joseph Lawlor -- resigned from the force , pleaded guilty to the kicking charges and will serve three months in prison , local news site ctpost.com reported . The incident in May 2011 was caught on video and posted to YouTube . The unsteady shot begins with the nattering sound of a Taser , before the lens sways over to a man on the ground . Two police officers appear to try to cuff him , then both of them kick him . A third officer , African-American , pulls up in a squad car and launches one small kick at the detained man lying on the ground . Whoever wrote the racist letter apparently did n't like that Higgins was acquitted alone and threatened his life for not going along with his convicted colleagues . `` You better watch your back . We know where you live . Your face was all over the newspaper . Remember you have no duty weapon to defend yourself , '' it read . Local news site ctpost.com posted a copy of the letter online . CNN 's Rick Martin and Amanda Watts contributed to this report .
