( CNN ) -- Thirteen Tennessee juveniles escaped from the Woodland Hills Youth Development Center on Friday night , the same juvenile detention center in Nashville where 32 escaped earlier this month . That 's an average of more than 1Â½ escapes per day . By Saturday morning , 12 of the 13 most recent escapees had been recaptured and brought to a juvenile court detention in Nashville to face additional charges , according a Tennessee Department of Children 's Services ( TDCS ) statement . A 16-year-old `` with a record that includes theft , assault and runaway '' remains at large . Two of the 32 teenagers who escaped back on September 1 are still on the lam . According to its website , Woodland Hills is for `` delinquent male youth '' between the ages of 13 and 19 that have committed at least three felonies . Among those rounded up from the latest jailbreak , `` many , if not all , of them have been involved in the previous two incidents , '' the TDCS statement said . Wait : Previous two ? In May , a group of teens broke out through a window and flipped a gate switch in an unsuccessful attempt to free others , according to CNN affiliate WSMV-TV in Nashville . `` Since the last set of escapes , the department has been rapidly upgrading security , '' TDCS said . `` Aluminum panels that students were able to kick through have been replaced with steel ... a project to reinforce the perimeter fence with concrete at the base is nearly complete . '' But TDCS , which operates the Woodland Hills facility , says its guards `` have few methods to control the youth ... they do not have weapons or pepper spray . '' The only thing they do have , according to the TDCS website , is a radio to call for help . Another problem , it would seem , is that the delinquent felons in lockup are not actually allowed to be locked up . `` Because of a decades old court settlement , the youth are not allowed to be locked inside their rooms , '' it said in a Saturday statement . According to an account of the incident provided by TDCS , Friday 's escape occurred after two inmates -- which it refers to as students -- overpowered a guard that was making his rounds . `` He was assaulted , and the students took his radio and keys . The other youth in the dorm came out of their unlocked rooms . '' The group then made its way to the perimeter gate , where one of them `` was able to wriggle through a gap between the fence and the gate '' and make it over to the guard house -- which he was able to break into by throwing a rock through the window . Once inside , he flipped the electric switch that opened the gate , liberating his comrades . Woodland Hills said two of its staff members were injured in the escape , one was treated at the scene , while the other was taken to a Nashville hospital . CNN 's Carma Hassan and Joe Sutton contributed to this report .
