( CNN ) -- Police in Boise , Idaho , said late Monday that they have made an arrest in connection with a break-in at a local zoo and the death of a patas monkey there . Michael J. Watkins , 22 , faces two felony charges , burglary and grand theft . `` I speak for many of us in the police department and the community who were angered and outraged over this senseless crime , '' said Boise Police Chief Michael Masterson . `` As usual , it was a combination of a citizen tip and good police work that led us to the arrest in this case . '' Police were called to Zoo Boise early Saturday morning by a guard who reported a burglary in progress . The security guard saw two men , one inside the zoo and one outside . They ran . During an unsuccessful search for the man inside the zoo , police and zoo employees found a patas monkey that was seriously injured near an exhibit where the suspect was last seen . The animal died ; the cause of death was determined to be blunt force trauma to the head and neck . Following citizen tips and information gleaned from the investigation , police arrested Watkins in Washington County , Idaho , where he remains in custody . He has injuries on his upper torso , but police have not yet been able to determine the cause of those injuries , Masterson said . The police chief declined to speculate on the suspect 's motives . He said he does not expect the other man the guard saw at the zoo to be criminally charged . Zoo Boise still has one patas monkey that the staff is giving extra attention in the wake of the other 's death . `` For the short time , he is OK being by himself , but that 's not a long-term solution . Monkeys need to be housed in social groups , and so ... we are actively trying to find another patas monkey that we might be able to bring the zoo , '' said Steve Burns , the zoo 's director . He said members of his staff were confused and angry when he first told them what happened . `` They kept asking why and I did n't have an answer for them , '' he said . CNN 's Greg Morrison contributed to this report .
