Tyler police are asking for help to find a group of men who robbed three people at gunpoint at separate locations Sunday night.

At 9:38 p.m., officers were called to 5700 block of Mustang Trail, where a man said two black men robbed him at gunpoint, according to a news release. The victim said the men, wearing dark hooded sweatshirts, struck him in the back of the head with a handgun and stole his phone.

He received minor injuries from the strike.

At 10:12 p.m., officers were called to 1900 block of Sybil Lane, according to a news release. A woman said two black men in dark hooded sweatshirts came up to her, pointed a gun at her and stole her debit card. The men left on foot, and she was not injured.

Then at 10:57 p.m., officers were called to 2100 block of West Jackson Street for a residential burglary. A woman said three black men knocked on her door, and when she answered, they entered her home, pointed a handgun at her and demanded money, according to a news release.

She said one of the men as heavy set, wearing a dark hooded sweater and another was tall and thin wearing a black T-shirt.

The men stole two cellphones and left on foot. The woman was not injured.

Because the descriptions in each incident are similar, police suspect the cases are related.     

These crimes are under investigation.  Anyone with information is asked to call the Tyler Police Department at 903-531-1000 or Tyler/Smith County Crimestoppers at 903-597-CUFF.   

Crimestoppers will pay up to $1,000 for information that leads to the arrest and charges filed against the suspects in this case or any other felony case.
