Crawley Town have signed defender Sonny Bradley from Portsmouth for an undisclosed fee.
The 22-year-old has penned a two-year contract with Town to become their fifth summer signing.
Manager John Gregory said: "Sonny is a commanding defender and someone I have been targeting for some time.
"We have good depth in our central defensive positions now but Sonny will be challenging the others for a regular place. There was a lot of interest in him, I'm delighted to have signed him."
