An indictable offense can be defined as an offense that can only be tried on indictment after the initial hearing to find out whether or not there is prima facie case to answer. A crime of similar nature is considered as a felony in United States. It also proceeds after indictment.
This is an offense where there is enough evidence and the grand jury thinks that the defendant must be charged with felony. Crimes in this category mainly include murder, kidnapping, manslaughter, rape, robbery, conspiracy, arson and other major crimes.
