Another attack method,
plofkraak, is to seal all openings of the ATM with
http://en.wikipedia.org/wiki/Silicone and fill the vault with a combustible gas or to place an explosive inside,
attached, or near the ATM. This gas or explosive is ignited and the vault is opened or distorted by the force of the resulting explosion and the criminals can break in.
I'd like to know whether the inserted adverbial past participle "attached" modifies "place an explosive inside or near the ATM."
Thank you in advance for your help.
