Hong Kong protests: Students fight police with petrol bombs, bows and arrows

The campus of one of Hong Kong's top universities turned into a battleground on Tuesday as student protesters fought with police well into the night.

After police entered the campus, protesters set up roadblocks, formed human chains to pass supplies, and made weapons including petrol bombs.

Others fought back with bows and arrows, as police fired volleys of tear gas and rubber bullets at the crowd.

The BBC spoke to some of the students at the scene.
