RICHARDSON, Texas - A police officer and a civilian have been shot and a gunman is barricaded in an apartment in a complex in a North Dallas suburb.

The incident happened about 7 p.m. Wednesday as an officer was checking a report of a man screaming at an apartment complex in Richardson, Texas.

A police spokesman said the conditions of the officer and the civilian weren't known, but that the officer had been taken to a hospital in nearby Plano.

Meanwhile, the spokesman said police had the apartment covered from which the gunman was still firing, apparently at random.
