Toronto police believe robbery may have been the motive behind the killing of the owner of a local tattoo and piercing shop.

The lifeless body of 47-year-old Wasfi Ghalban was found inside his second floor apartment at 200 Wellesley St. E. last month.

Police say that a friend contacted them after not hearing from Ghalban for several days. Officers responded to that call at 11:45 p.m. on Dec. 3, 2014.

"Mr. Ghalban was observed to have significant trauma to his body," Det-Sgt. Mike Carbone told reporters during a news conference at police headquarters on Wednesday morning.

But Carbone said he is not willing to identify the cause of Ghalban's death at this time.

"It appears that this was a targeted attack and robbery may have been a motive," said Carbone.

He did not say what, if anything, was taken from Ghalban's apartment.

"I don't want to discuss what the evidence revealed inside the dwelling, however, we're satisfied at this point that robbery was certainly a motive for this attack," he said.

Police have collected surveillance video from the building and on Wednesday released images of two persons of interest in the case.

The two men were seen entering the lobby at the 200 Wellesley St. E. building on the evening of Dec. 1, 2014, two days before Ghalban's body was found.

One of the men heads to a set of elevators, while another appears to enter a stairwell.

Carbone is asking for these individuals to contract police. But investigators also want to speak to anyone who may have contact with them.
