ARLINGTON, Texas (CBSDFW.COM) – Police in Arlington have arrested an 18-year-old for aggravated robbery and believe he may be involved in other violent crimes in the area.
Surveillance video was released from the incident on Monday at a 7-Eleven in southeast Arlington involving the suspect, Osagie Ayanru. Police said he allegedly stabbed a store clerk during a robbery even though she complied.
The video also shows the suspect appearing to stomp on her and kick her while she was on the ground before he ran away.
Police believe Ayanru may be connected to an attack on Wednesday, where a couple was stabbed and robbed while walking in the 6400 block of South Collins Street.
The two victims were taken to the hospital, but one of them, later identified as 47-year-old Islam Sahmi Duly, died from his injuries.
Police said they also believe the suspect stole a vehicle from the same 7-Eleven store on Wednesday before the couple was attacked.
According to police, they believe the suspect was driving away from scene of the attack on Wednesday when the car he was in hit a woman who was walking her dog in the 900 block of Southeast Parkway.
A suspect jumped out of the car and tried to rob the woman, police said. Her dog was killed in the crash.
According to police, the woman told investigators she could hear someone yelling, “grab her wallet, grab her wallet,” as she lied on the ground.
Police said they are still investigating if there are other suspects involved.
Ayanru was arrested after police said the store clerk who was attacked was shown a picture and was able to recognize him.
He is charged with aggravated robbery and theft of a vehicle.
“We were all appalled at the level of violence in each of these cases especially as you watch the video what happened to the store clerk who was cooperative and what happened to our citizens who were just walking our neighborhoods,” Lt. Chris Cook said.
