ACT police have executed five search warrants and spoken to "a number of youths," people under the age of 18, while investigating alleged assaults on gay men.
Three men were allegedly assaulted after being lured to locations on dating app Tinder in July this year.
"Following a thorough investigation, five search warrants have been executed at various residences in the ACT and NSW throughout the last fortnight," police said.
Some of those were executed on Thursday.
"As a result of these search warrants, several electronic devices have been seized, and a number of youths have been spoken to by police," they said.
"At this time no arrests have been made in relation to these incidents, however investigations remain ongoing."
Police have previously said that four men allegedly attacked a man lured to a Denman Prospect house via Tinder on July 16.
In a second alleged incident, seven or eight men attacked a different man in Red Hill on July 20.
"During the assault, the group allegedly shouted homophobic slurs at the victim, as well as demanding money and attempting to take his wallet and keys," police said.
"The man was able to escape, but was allegedly pursued on foot by the group, who continued the assault in front of another residence."
In the third alleged attack, also on July 20, five to eight men wearing face coverings attacked another victim in Red Hill.
Police said:
"Incidents such as these are taken very seriously, and anyone who has been a victim of an assault under similar circumstances is encouraged to contact police on 131 444."
