Water bottles thrown at police in Ferguson; more arrests

Ferguson, Missouri (CNN) -- Police chased young men down Ferguson's streets and made arrests, as water bottles flew again shortly before midnight Tuesday.

Protesters locked hands in front of the police line, while some urged the crowd to remain peaceful.

The police presence rose significantly, as did tensions.

Until then, the streets had been calm, as a much smaller crowd milled about, holding signs and chanting.

A few hundred people walked up and down a small area past journalists' cameras. And as hours passed, the crowd thinned down to a few dozen.
