A Penn State professor accused of performing sex acts on his pet dog begged police to shoot him during his arrest for the disturbing allegation. 

Themis Matsoukas, 64, was allegedly caught in the act on surveillance cameras by the bathrooms at Rockrock State Forest, wearing a mask while half naked except for socks and shoes.

After police tracked him down and showed up on his doorstep, Matsoukas allegedly became 'visibly nervous', before telling officers: 'What do I have to do to get you to shoot me? I need to die.' 

During the arrest, he reportedly then conceded that he carries out the depraved act to 'blow off steam'.

The Pennsylvania Department of Conservation and Natural Resources launched an investigation after security cameras intended to monitor thieves captured the lewd acts on film. 

Matsoukas allegedly performed the acts in and around the forest's parking lot and restrooms, where police say he targeted his pet collie sexually. 

The lurid habit also saw the award-winning professor try and record himself performing the acts with an electronic tablet, reports Fox43

And according to the affidavit, Matsoukas could be seen in the surveillance footage masturbating near a women's public restroom, before 'engaging in a sexual act with a dog'. 

It is alleged Matsoukas' had been carrying out the depraved act since 2014. After the suspect was caught again in May, investigators tracked his car and were able to obtain a search warrant for his home and vehicle. 

Officials reportedly sought to link the professor with items from the park footage including a North  Face backpack, a ski mask, an electronic tablet, and his pet collie.

But when investigators allegedly caught the suspect, Matsoukas' began to 'panic', while initially denying any knowledge of the perverted acts, charging documents claim. 

When officers said they believed they knew why they were at his door, the professor fell into despair and asked the officers to shoot him. 

Questioned about his motive for the bizarre fetish, he allegedly told investigators: 'I do it to blow off steam'. 

Officers reportedly spotted the collie in Matsoukas' home that matched the dog in the park surveillance footage. 

They also recovered items similar to those worn by the man in the videos, along with three electronic tablets, according to the charging documents. 

He is facing charges of open lewdness, indecent exposure, sexual intercourse with an animal, and summary charges of cruelty to animals and disorderly conduct. 

His attorney, Matthew McClenahen, said Wednesday: 'It would be inappropriate to make any comment at this time'. 

Penn State University said after his arrest he has now 'been relieved of his responsibilities and is on leave.' He had been at the college since 1991, where he won several distinguished teaching awards.
