An 18-year-old man has been arrested after police seized more than 500 cannabis plants from a property in Seaford.
Officers responded to reports of an altercation at a property in Sutton Road at about 21:30 BST on Sunday.
Following a search, 284 developed and 257 undeveloped plants were recovered across five rooms, Sussex Police said.
The man arrested, who was held on suspicion of cultivation of a Class B drug and money laundering, was later bailed pending futher inquiries.
Det Con Marcus Cox, of the East Sussex Criminal Investigation Department, said: “This is another example of our commitment to disrupt and reduce drug-related activity in Sussex.”
