"A person has been arrested and a search warrant issued to potentially retrieve remaining kit," Hollioake suggested on Twitter.
The success of the Western Australia police in recovering the stolen kit from a house in Applecross, in Perth's suburbs, has been hailed as an example of cricket's virtual community working together on social media for the general good.
According to Hollioake, the kit was recovered in several stages. The collection, which includes England shirts, sweaters, bats and helmets, is treasured by the family since his death ten years ago when his sports car spun out of control and hit a wall in south Perth.
"Kit turning up by the hour - probably 75% of it back now," he tweeted. "No doubt in my mind that you guys instigated us getting it back.
"On a positive note I know my bro would be happy everyone was talking about him again. He loved the spotlight. He probably arranged the theft himself from heaven."
