Three teenaged boys are charged with arson after a fire that destroyed a playground on the Dartmouth waterfront.

The play ship was torched on Feb. 25 just outside Alderney Landing.

Now, a 16 year-old boy and two 15 year-olds have been charged.

Halifax police say they expect to make more arrests.

Officials with the Halifax Regional Municipality said it will cost $100,000 to replace.

More than a decade ago, the Kiwanis Club paid thousands of dollars to build the playground. It's one of the few wheelchair accessible parks around the city. The city said any rebuild will also be accessible.
