Rihanna, who was spotted heading to the gym situated near her home in Soho, New York, on Monday, July 13, seemingly looked subdued and strange as the paparazzi took photos of her.
While keeping her poise inher gym attire of black leggings, simple black shirt and big sunglasses, Rihanna tried to look calm after her alleged stalker sent her several alarming threats on social media.
Following the news, reports say that the authorities have continued to search for Riri's alleged stalker who sent threatening tweets, including a photo of one gun and bullets.
The man, whom Rihanna referred to as her rude stalker, had reportedly posted a photo of himself outside Riri's home on April 30. However, the suspect immediately disappeared as the police arrived at the area.
The singer also revealed that the man sent her a couple of threatening messages. On Sunday, July 12, some reports have pointed out the names of Alex Mercer and Ralph Alexander as the main suspects as the authorities were led to their Twitter accounts during investigation.
In the said tweet of the alleged Rihanna stalker, he wrote: "Should of killed @rihanna a minute back I would be good right now."

The suspect added that he also uses guns as a weapon. "Sorcery is a weapon I use guns," he wrote. "Can't. Use hands."
Rihanna previously had stalker issues in the past. A man was arrested by the authorities and was escorted by three policemen and Riri's personal bodyguard after he attempted going inside the singer's apartment building in New York.
In July last year, another 53-year old man was also arrested for delivering strange and frightening messages to her Soho apartment.
Despite the threats to the singer's safety, Rihanna has continued on with her singing career. The record breaking artist has recently topped the 2015 RCAA list, selling a total of 100 album units.
