NATION : 2,500 Demonstrate for AIDS Help

<i> From Times wire services </i>

An estimated 2,500 demonstrators demanding that Mayor Edward I. Koch do more to help AIDS victims swarmed around City Hall today, snarling rush-hour traffic while police hauled more than 100 off to jail.

The protesters from AIDS Coalition to Unleash Power, or ACT-UP, accused Koch’s government of ignoring the acquired immune deficiency syndrome crisis while hospitals overflow with people dying of complications of it.

The demonstrators shouted “Act Up, fight back, fight AIDS!” Some sat down in the middle of the street, stopping vehicles as they crossed the Brooklyn Bridge into Manhattan. Police rushed those demonstrators to prevent traffic tie-ups, and traffic returned to normal 15 minutes later.
