Police have arrested a man they believe to be connected to two sex crimes in Chantilly that were reported weeks apart.
According to the Fairfax County Police Department, the unidentified man tried to grab a woman on June 3 and entered a home and tried to sexually assault a woman on May 18.
Officers were called to a home in the 14500 block of Northeast Place around 11:30 a.m.
When officers arrived, they learned a woman and her mother were outside. The victim's mother went to visit a neighbor's house when the suspect walked up and grabbed at the woman in an intimate area and put her in a chokehold.
When the victim's mother ran towards the assault, the man ran away.
Police later arrested 20-year-old Hien The Dinh, of Stafford, Virginia.
Evelyn, who lives on Northeast Place in Chantilly, says Monday morning she was inside her home when someone started banging on her front door. When she opened it she found her neighbor.
"She was very scary, crying," said Evelyn.
She says the woman told her she'd be sexually assaulted, and that her Mom was chasing after the suspect.
"She said I am very worried because my Mom went after this man he touched me and I am scared for my Mom," said Evelyn.
She told WUSA9 she was relieved to learn that the suspect had been arrested.
Video from a neighbor's home security camera captured the man as he was running away that morning.
"It was broad daylight. A man came up and sexually assaulted her. He grabbed her in an intimate area and got her into a chokehold," said Sgt. Jacob Pearce with the Fairfax County Police Department.
He told WUSA9 as Detectives believe the suspect may also be responsible for a second assault in May. Investigators say a man was able to get into a home in the 14500 block of Iberia Circle and tried to sexually assault a woman inside. The woman was able to get away and call police but the suspect left before officers arrived.
"A lot of the descriptors, the type of assault that occurred, a lot of it was very similar," said Sgt. Pearce.
As the investigation continued, they also realized there were similarities to a case being investigated in Loudoun County. On May 10, police say a woman was sexually assaulted on Loudoun County's Northern Virginia Community College Campus.
Fairfax County Police say there will be a news conference Friday morning, where they will release more details about the suspect.

Detectives believe there may be a possible link between this attack and a May 18 sexual assault.
