( CNN ) -- Authorities in Chandler , Arizona , said they believe the gunman who held hostages at a restaurant is the same man who fled into a mall after opening fire on members of a crime task force . The man who surrendered at the Baja Fresh restaurant is not the federal fugitive that U.S. marshals thought they might have spotted earlier outside the Chandler Fashion Center , said Police Sgt . Joe Favazzo . After a thorough police sweep , the mall reopened later Wednesday , Detective David Ramer said . `` We believe there is only one suspect here , '' Favazzo said . A woman who fled the restaurant , which is near the mall , told CNN she witnessed the man , who police later identified as Adam Hernandez , being taken into custody . Baja Fresh customer Leyda Schultz told CNN that a gunman held at least two employees after ordering customers to leave . Schultz said she witnessed the man being taken into custody shortly before 2 p.m. Favazzo said it was not clear whether the two were patrons or employees . The gunman apparently fired warning shots at the restaurant . Marshals and other members of a task force had confronted a suspect outside the Sears store on the west side of Chandler Fashion Center , said Arizona Department of Public Safety spokesman Robert Bailey . The suspect opened fire , and officers returned it , Bailey said . The suspect was being sought in an armed robbery , Chandler police said . The suspect entered the Sears , and the mall was evacuated and surrounded , Bailey said . A hostage situation was reported about 12:30 p.m. at the nearby Baja Fresh , he said . Favazzo said officers lost sight of the suspect in the mall . Marshals earlier Wednesday said the suspect seen at the mall may be fugitive Daniel Munoz Perez , who was mistakenly released last month . Marshals were trailing a vehicle known to be driven in the past by Perez , Jeff Carter with the U.S . Marshals said . When the suspect -- later determined to be Hernandez -- opened fire outside the mall , it seemed to confirm suspicions that they were following Perez . Carter said the men looked alike and called it a case of `` misidentification . '' Perez is being sought for aggravated assault for allegedly shooting at a police officer in December , authorities said . According to U.S . Marshal David Gonzales , Perez was released from the Pinal County Sheriff 's Office on December 16 . The U.S . Marshals Service has been looking for him since . Perez is accused of shooting at Arizona Department of Public Safety officers December 11 outside a home in Casa Grande , according to CNN affiliate KPHO . Perez , 25 , was injured by gunfire in the shootout with the public safety officers , according to KPHO . He was admitted to a Phoenix hospital and was later held in another county 's jail before being turned over to Pinal County , KPHO said . But the Pinal County Sheriff 's Office said it never received the charging paperwork for Perez , and he bonded out on an misdemeanor warrant . The bond was $ 320 , KPHO said .
Chandler Fashion Center reopens after police sweep . The center was closed for a week in September because of the investigation into an alleged sexual assault at one of its stores. Authorities believe restaurant gunman , man who fled to mall are the same person . Suspect is not federal fugitive Daniel Munoz Perez as previously thought , police say .
