May Day protests: LAPD issues tactical alert
The Los Angeles Police Department on Tuesday issued a tactical alert as the May Day protests in downtown L.A. stretched into the evening.
Authorities have not said when they will disperse the crowd, but did say they will not allow the protest to continue all night.
A tactical alert allows the department to keep officers on past the end of their shift.
"It increases our ability to deploy officers if the need breaks out," said Officer Karen Rayner, an LAPD spokeswoman.
At least 1,000 demonstrators, many from the Occupy movement, convened at Pershing Square on Tuesday evening to call for immigration reform and workers' rights.
That gathering came shortly after a tense standoff between police and Occupy protesters.
A police official said a female officer was struck in the head with a skateboard and taken to a hospital. The impact of the blow dented her helmet, the official said, but her injury appeared not to be life-threatening.
At least 13 arrests have been made throughout the demonstrations, 10 during a protest at Los Angeles International Airport and three in downtown L.A. Overall, however, officials said most of the thousands of protesters were nonviolent.
