Baltimore Ravens RB -- I Was Robbed at Gunpoint ... In Miami Beach Hotel

Baltimore Ravens running back Terrance West says he was jacked TWICE on the same day in a Miami Beach hotel ... and says one of the perps threatened to kill him.

The story is insane ... West -- a 3rd round pick in the 2014 draft -- says he was at the Metropole South Beach hotel with a buddy back in February when all hell broke loose.

According to court docs obtained by TMZ Sports, West says he was approached by 2 women on Feb. 27th -- chatted them up -- and then parted ways without any plans to meet up later.

But West says the women went to the front desk at the hotel and asked for a key to West's suite -- without authorization from West or his friend -- and the guy at the desk GAVE IT TO THEM!

Then, West says, the hotel provided a bellman who escorted the women to the suite -- where they proceeded to steal 2 Rolex watches that belonged to West and his pal.

West says when he realized the watches were missing, he notified the front desk and filed a report with police.

THEN IT GETS CRAZIER ...

West says an hour later, someone knocked on his hotel room door -- and he opened it up thinking it was the cops following up. He was wrong.

Instead, West claims an unidentified man -- who appeared to have a gun -- forced his way into the room and threatened his life ... demanding cash and valuables.

West says the man took off with $5,000 in cash, Louboutin shoes and other expensive stuff.

Fortunately, West says he was not harmed -- but he's suing the hotel for more than $50,000 claiming it was their fault he was hit TWICE in the same day.
