Good morning @metronewyork. It's gonna be hot, hot, hot out there today. The Metro6@7 will point you to our hot weather tips and some must-reads, including news that subway crime is up and arrest are down. Speaking of arrests, find out why P. Diddy is in hot water.

SUBWAY CRIME SOARS
Crime is up and arrests are down in the subways. Not good. Metro's Wendy Joan Biddlecombe and Miles Dixon haver the latest on the trouble down under.

DIDDY GOES DOWN
P. Diddy. Puffy. Sean Combs. We've lost track. But Metro's Ned Ehrbar knows this: The music  mogul was arrested following an altercation that involved the use of a kettlebell weight as a weapon on his son's coach. Allegedly.

BEAT-THE-HEAT STRATEGIES
Tuesday’s forecast shows a high of 94 degrees and ridiculous humidity that will make it feel like 100. Now that summer has officially started, New Yorkers are using their best strategies to deal with the hot and humid weather.

REFORMING RIKERS
If the politicians won’t institute reform in New York, U.S. Attorney Preet Bharara seems on the ready to force their hand. His latest  victory: Major changes, including the appointment of a federal monitor, at New York City’s notorious jail on Rikers Island.

HILLARY SHUNS BROOKLYN
Busted. Turns out Hillary Clinton  rarely, if ever, shows up in Brooklyn at her much-ballyhooed headquarters.  Apparently, Clinton prefers her Midtown digs on the 27th floor of a West 45th St. tower to 1 Pierrepont Plaza.

SUSTAINABLE SEAFOOD
It's Sustainable Seafood Week, and Metro's Eva Kis asks a chef and a fishmonger why the key to better seafood is making our diets more local, and why sustainability is important for our health, too. Some fascinating and eye-opening stuff.
