PARIS: A plain clothes police officer shot into a crowd of skirmishing soccer fans Thursday as he tried to protect a supporter of the Hapoel Tel Aviv team, killing one person and injuring another, police said.

The 11 p.m. (2200 GMT) incident at a McDonald's fast food restaurant near the Parc des Princes stadium occurred after Hapoel Tel Aviv's 4-2 victory over Paris Saint-Germain in a UEFA Cup match.

The officer, who was not identified, was trying to protect a Hapoel Tel Aviv fan set upon by some 150 PSG supporters, police said. He lobbed tear gas when the crowd went after him then fired two shots, "having been driven into a corner," police said.

Two people were injured, with one dying later, police said. The victims were not identified.

The Paris prosecutor's office and the National Police General Inspection unit, which probes incidents involving law enforcement officers, were investigating, police said.
