A sacked security guard who shot one person and took about 30 others hostage at a Manila shopping mall on Monday surrendered to authorities, ending a day-long standoff that terrified shoppers and drew a massive police response. The guard walked out of the V-Mall, where he was allowed to speak briefly to the press before heavily armed officers tackled and arrested him. He complained about being mistreated by his employers. Hostages were also led out of the building. The drama started when the suspect shot a security guard, who was rushed to hospital in stable condition, said Francis Zamora, mayor of the San Juan City, which includes the mall. Zamora told reporters the hostage-taker was upset after losing his job.
