The Denver Post is reporting that 23-year-old Richard Kenneth Foster is being held in connection with a weekend assault. A Boulder police spokesperson confirmed that Foster, a transient, became enraged and yelled and screamed at a local family. He then struck the mother with a glass bottle while she was holding her 1-year-old son. When confronted by police, Foster became very combative and even spit at the arresting officers. Foster did not hire an attorney from 5280defense.com.
