( CNN ) -- A Baltimore man pleaded guilty Thursday in connection with a plot to bomb a military recruiting station in retaliation for U.S. forces killing Muslims overseas , authorities said . Antonio Benjamin Martinez , 22 , a Muslim convert who also goes by the name Muhammad Hussain , pleaded guilty to use of a weapon of mass destruction against federal property in connection with the plot involving an Armed Forces Career Center in Catonsville , Maryland , the Justice Department said . The guilty plea was part of a plea agreement with prosecutors , authorities said . If the court accepts the plea , Martinez will be sentenced to 25 years in prison . Sentencing is set for April 6 . Martinez was arrested in December 2010 after attempting to detonate an inert device supplied to him by an undercover FBI agent , authorities said . According to the plea agreement , Martinez first raised the subject of attacking military targets with an FBI confidential source in October 2010 . During recorded conversations that followed with the source and later an undercover FBI agent , Martinez identified the recruiting station as a target and `` spoke about his anger toward America , his belief that Muslims were being unjustly targeted and killed by the American military , and his desire to commit jihad to send a message that American soldiers would be killed unless the country stopped its 'war ' against Islam , '' federal prosecutors said . He also articulated his beliefs in postings on his Facebook page and in two Facebook chats with the source , the Justice Department said . He attempted to recruit people to join in the plot , authorities said . All of them declined , and one attempted to dissuade him from it . But Martinez agreed to meet the confidential source 's `` Afghani brother '' -- the undercover FBI agent -- after the source told him the `` brother '' would be interested in helping . He told the agent that he wanted jihadist activities to be his `` profession , '' authorities said . On December 8 , he met the source to drive to a public parking lot near the recruiting center and attempted to detonate the device . On the way , he had the source videotape him saying he would continue to fight `` against the oppressors until those who waged war with Islam stopped their actions , '' the Justice Department said . `` Martinez admitted that the bomb was intended to kill military service members who worked in the building , '' authorities said . `` This is an example of another successful prosecution that resulted from outstanding partnerships between the Muslim community and law enforcement , '' said Richard McFeely , FBI special agent in charge , in a Justice Department statement . `` As the threat from homegrown violent extremists remains high , the FBI and our police partners rely on a two-way flow of information with the Muslim community at large . Together we are working to stop those that have perverted the Islamic faith into something it is not . '' Martinez 's attorney argued in a December 2010 hearing that federal authorities set his client up in a sting operation . But Rod Rosenstein , the U.S. attorney in Baltimore , said at the time federal authorities `` do n't initiate these investigations unless there is a credible allegation that the defendant himself ( has ) already expressed an intent to cause harm . And secondly , throughout the investigation , the FBI seeks to clarify the defendant 's intent , challenging him , making certain that he 's expressly told that he does n't need to go forward with this .
