As Feds closed in on Boston bomb suspect Dzhokhar Tsarnaev  he reportedly scrawled  “F**** America" on the side panel of his boat hideout.

Massachusetts police also said they found "Praise Allah" on the boat's side panels and several anti-American rants about  Iraq, Afghanistan and "the infidels".  

ABC News reported that an official said what was appeared to be a cell phone picture of the phrase "Praise Allah," written in black ink, with a bullet hole above it was believed to have been written by Tsarnaev when he was hiding inside the dry-docked boat in Watertown, Mass.

The discovery of the alleged hate messages intensified an already tense situation between the FBI and local Massachusetts police when feds believed several Boston police officers and state police had taken cell phone pictures of the blck ink scrawl.

According to ABC News, feds demanded the cellphones of all attending officers at the scene to be confiscated to avoid the photos becoming public prior to being entered as key prices of evidence at Tsarnaev trial.

 Massachusetts State Police and Watertown police had denied the existence of the writings when first queried.

Now, both departments have referred reporters to the FBI and a federal law enforcement official has confirmed writing had been discovered inside the boat.
